  • 23warning: assignment makes pointer from integer without a cast

    - by FILIaS
    Im new in programming c with arrays and files. Im just trying to run the following code but i get warnings like that: 23 44 warning: assignment makes pointer from integer without a cast Any help? It might be silly... but I cant find what's wrong. #include<stdio.h> FILE *fp; FILE *cw; char filename_game[40],filename_words[40]; int main() { while(1) { /* Input filenames. */ printf("\n Enter the name of the file with the cryptwords array: \n"); gets(filename_game); printf("\n Give the name of the file with crypted words:\n"); gets(filename_words); /* Try to open the file with the game */ if (fp=fopen("crypt.txt","r")!=NULL) //line23 { printf("\n Successful opening %s \n",filename_game); fclose(fp); puts("\n Enter x to exit,any other to continue! \n "); if ( (getc(stdin))=='x') break; else continue; } else { fprintf(stderr,"ERROR!%s \n",filename_game); puts("\n Enter x to exit,any other to continue! \n"); if (getc(stdin)=='x') break; else continue; } /* Try to open the file with the names. */ if (cw=fopen("words.txt","r")!=NULL) //line 44 { printf("\n Successful opening %s \n",filename_words); fclose(cw); puts("\n Enter x to exit,any other to continue \n "); if ( (getc(stdin))=='x') break; else continue; } else { fprintf(stderr,"ERROR!%s \n",filename_words); puts("\n Enter x to exit,any other to continue! \n"); if (getc(stdin)=='x') break; else continue; } } return 0; }

  • Reducing Integer Fractions Algorithm - Solution Explanation?

    - by Andrew Tomazos - Fathomling
    This is a followup to this problem: Reducing Integer Fractions Algorithm Following is a solution to the problem from a grandmaster: #include <cstdio> #include <algorithm> #include <functional> using namespace std; const int MAXN = 100100; const int MAXP = 10001000; int p[MAXP]; void init() { for (int i = 2; i < MAXP; ++i) { if (p[i] == 0) { for (int j = i; j < MAXP; j += i) { p[j] = i; } } } } void f(int n, vector<int>& a, vector<int>& x) { a.resize(n); vector<int>(MAXP, 0).swap(x); for (int i = 0; i < n; ++i) { scanf("%d", &a[i]); for (int j = a[i]; j > 1; j /= p[j]) { ++x[p[j]]; } } } void g(const vector<int>& v, vector<int> w) { for (int i: v) { for (int j = i; j > 1; j /= p[j]) { if (w[p[j]] > 0) { --w[p[j]]; i /= p[j]; } } printf("%d ", i); } puts(""); } int main() { int n, m; vector<int> a, b, x, y, z; init(); scanf("%d%d", &n, &m); f(n, a, x); f(m, b, y); printf("%d %d\n", n, m); transform(x.begin(), x.end(), y.begin(), insert_iterator<vector<int> >(z, z.end()), [](int a, int b) { return min(a, b); }); g(a, z); g(b, z); return 0; } It isn't clear to me how it works. Can anyone explain it? The equivilance is as follows: a is the numerator vector of length n b is the denominator vector of length m

  • How should I define a composite foreign key for domain constraints in the presence of surrogate keys

    - by Samuel Danielson
    I am writing a new app with Rails so I have an id column on every table. What is the best practice for enforcing domain constraints using foreign keys? I'll outline my thoughts and frustration. Here's what I would imagine as "The Rails Way". It's what I started with. Companies: id: integer, serial company_code: char, unique, not null Invoices: id: integer, serial company_id: integer, not null Products: id: integer, serial sku: char, unique, not null company_id: integer, not null LineItems: id: integer, serial invoice_id: integer, not null, references Invoices (id) product_id: integer, not null, references Products (id) The problem with this is that a product from one company might appear on an invoice for a different company. I added a (company_id: integer, not null) to LineItems, sort of like I'd do if only using natural keys and serials, then added a composite foreign key. LineItems (product_id, company_id) references Products (id, company_id) LineItems (invoice_id, company_id) references Invoices (id, company_id) This properly constrains LineItems to a single company but it seems over-engineered and wrong. company_id in LineItems is extraneous because the surrogate foreign keys are already unique in the foreign table. Postgres requires that I add a unique index for the referenced attributes so I am creating a unique index on (id, company_id) in Products and Invoices, even though id is simply unique. The following table with natural keys and a serial invoice number would not have these issues. LineItems: company_code: char, not null sku: char, not null invoice_id: integer, not null I can ignore the surrogate keys in the LineItems table but this also seems wrong. Why make the database join on char when it has an integer already there to use? Also, doing it exactly like the above would require me to add company_code, a natural foreign key, to Products and Invoices. The compromise... LineItems: company_id: integer, not null sku: integer, not null invoice_id: integer, not null does not require natural foreign keys in other tables but it is still joining on char when there is a integer available. Is there a clean way to enforce domain constraints with foreign keys like God intended, but in the presence of surrogates, without turning the schema and indexes into a complicated mess?

  • Decimal Value is Zero when it should be 0.0x

    - by Mike Wills
    If this was previously talked about, I'm sorry, I had a hard time searching on this. I am calculating a depreciation rate. One portion of our calculation is 1/life in months. My table stores this data in a decimal field. I tried test = 1 / estimatedLife; but the result of the calculation of test (which is defined as a decimal) is 0. Say the estimated life is 36 months. So 1/36 should equal 0.02777778. Any thoughts of what I am doing wrong? BTW, I changed the test to a double and had the same result.

  • MySQL - Calculating a value from two columns in each row, using the result in a WHERE or HAVING clause

    - by taber
    I have a MySQL db schema like so: id flags views done ------------------------------- 1 2 20 0 2 66 100 0 3 25 40 0 4 30 60 0 ... thousands of rows ... I want to update all of the rows whose flags / views are = 0.2. First as a test I want to try to SELECT to see how many rows would actually get updated. I tried: SELECT flags/views AS poncho FROM mytable HAVING poncho 0.2 But this only returns like 2 rows and I know there should be a lot more than that. It seems like it's calculating the poncho value on all rows or something odd. What am I doing wrong? Thanks!

  • How do you calculate div and mod of floating point numbers?

    - by boost
    In Perl, the % operator seems to assume integers. For instance: sub foo { my $n1 = shift; my $n2 = shift; print "perl's mod=" . $n1 % $n2, "\n"; my $res = $n1 / $n2; my $t = int($res); print "my div=$t", "\n"; $res = $res - $t; $res = $res * $n2; print "my mod=" . $res . "\n\n"; } foo( 3044.952963, 7.1 ); foo( 3044.952963, -7.1 ); foo( -3044.952963, 7.1 ); foo( -3044.952963, -7.1 ); gives perl's mod=6 my div=428 my mod=6.15296300000033 perl's mod=-1 my div=-428 my mod=6.15296300000033 perl's mod=1 my div=-428 my mod=-6.15296300000033 perl's mod=-6 my div=428 my mod=-6.15296300000033 Now as you can see, I've come up with a "solution" already for calculating div and mod. However, what I don't understand is what effect the sign of each argument should have on the result. Wouldn't the div always be positive, being the number of times n2 fits into n1? How's the arithmetic supposed to work in this situation?

    Hay i need help. I want to find all muliples of a number in PHP. I'm using something like this if($count != 20 ) to work out if $count is not equal to 20. but i also need this script to check if $count is not equal to 20,40,60,80,100,120,140,160 etc. Any ideas? I think i need to use the modulus symbol (%), but i don't know. Thanks

  • Doctrine MYSQL 150+ tables: generating models works, but not vice-versa?

    I can generate my models and schema.yml file based on an existing database. But when I try to do it the other way around using Doctrine::createTablesFromModels() i get an error: Syntax error or access violation: 1064 So either of these works: Doctrine::generateYamlFromDb(APPPATH .

  • Would making plain int 64-bit break a lot of reasonable code?

    - by R..
    Until recently, I'd considered the decision by most systems implementors/vendors to keep plain int 32-bit even on 64-bit machines a sort of expedient wart. With modern C99 fixed-size types (int32_t and uint32_t, etc.) the need for there to be a standard integer type of each size 8, 16, 32, and 64 mostly disappears, and it seems like int could just as well be made 64-bit. However, the biggest real consequence of the size of plain int in C comes from the fact that C essentially does not have arithmetic on smaller-than-int types. In particular, if int is larger than 32-bit, the result of any arithmetic on uint32_t values has type signed int, which is rather unsettling. Is this a good reason to keep int permanently fixed at 32-bit on real-world implementations? I'm leaning towards saying yes. It seems to me like there could be a huge class of uses of uint32_t which break when int is larger than 32 bits. Even applying the unary minus or bitwise complement operator becomes dangerous unless you cast back to uint32_t. Of course the same issues apply to uint16_t and uint8_t on current implementations, but everyone seems to be aware of and used to treating them as "smaller-than-int" types.

  • Quick question regarding this issue, Why doesnt it print out the second value(converted second value

    - by sil3nt
    Quick question, What have I done wrong here. The purpose of this code is to get the input into a string, the input being "12 34", with a space in between the "12" and "32" and to convert and print the two separate numbers from an integer variable known as number. Why doesn't the second call to the function copyTemp, not produce the value 34?. I have an index_counter variable which keeps track of the string index and its meant to skip the 'space' character?? what have i done wrong? thanks. #include <stdio.h> #include <string.h> int index_counter = 0; int number; void copyTemp(char *expr,char *temp); int main(){ char exprstn[80]; //as global? char tempstr[80]; gets(exprstn); copyTemp(exprstn,tempstr); printf("Expression: %s\n",exprstn); printf("Temporary: %s\n",tempstr); printf("number is: %d\n",number); copyTemp(exprstn,tempstr); //second call produces same output shouldnt it now produce 34 in the variable number? printf("Expression: %s\n",exprstn); printf("Temporary: %s\n",tempstr); printf("number is: %d\n",number); return 0; } void copyTemp(char *expr,char *temp){ int i; for(i = index_counter; expr[i] != '\0'; i++){ if (expr[i] == '0'){ temp[i] = expr[i]; } if (expr[i] == '1'){ temp[i] = expr[i]; } if (expr[i] == '2'){ temp[i] = expr[i]; } if (expr[i] == '3'){ temp[i] = expr[i]; } if (expr[i] == '4'){ temp[i] = expr[i]; } if (expr[i] == '5'){ temp[i] = expr[i]; } if (expr[i] == '6'){ temp[i] = expr[i]; } if (expr[i] == '7'){ temp[i] = expr[i]; } if (expr[i] == '8'){ temp[i] = expr[i]; } if (expr[i] == '9'){ temp[i] = expr[i]; } if (expr[i] == ' '){ temp[i] = '\0'; sscanf(temp,"%d",&number); index_counter = i+1; //skips? } } // is this included here? temp[i] = '\0'; }

  • Nullable One To One Relationships with Integer Keys in LINQ-to-SQL

    - by Craig Walker
    I have two objects (Foo and Bar) that have a one-to-zero-or-one relationship between them. So, Foo has a nullable foreign key reference to Bar.ID and a (nullbusted) unique index to enforce the "1" side. Bar.ID is an int, and so Foo.BarID is a nullable int. The problem occurs in the LINQ-to-SQL DBML mapping of .NET types to SQL datatypes. Since int is not a nullable type in .NET, it gets wrapped in a Nullable<int>. However, this is not the same type as int, and so Visual Studio gives me this error message when I try to create the OneToOne Association between them: Cannot create an association "Bar_Foo". Properties do not have matching types: "ID", "BarID". Is there a way around this?

  • Saving a select count(*) value to an integer (SQL Server)

    - by larryq
    Hi everyone, I'm having some trouble with this statement, owing no doubt to my ignorance of what is returned from this select statement: declare @myInt as INT set @myInt = (select COUNT(*) from myTable as count) if(@myInt <> 0) begin print 'there's something in the table' end There are records in myTable, but when I run the code above the print statement is never run. Further checks show that myInt is in fact zero after the assignment above. I'm sure I'm missing something, but I assumed that a select count would return a scalar that I could use above?

  • Processing an Integer Buried in a String in XSL

    - by justkt
    I have a stored time value which is of the format H:mm:ss. The hours may be any value from 0 up through several days. This data is sent in an XML tag and processed by XSL to be displayed. The display that I want is of the format: D days, HH:mm:ss (hours/minutes) Where the last tag shows hours if HH is greater than 0, minutes if it is 0. Given the original HH, which may be more than 24, I know I need the floor of HH / 24 to get the days value. Then the original HH % 24 gives me the leftover hours. I have also handled the minutes and hours question using xsl:when and xsl:if. It's getting days and hours from the hours value that has me stumped. EDIT So far, I'm looking at doing the following: Variable declaration <xsl:variable name="time"><xsl:value-of select="time" /><xsl:variable> <xsl:variable name="days"><xsl:value-of select="floor(substring-before(time, ':') / 24)" /></xsl:variable> <xsl:variable name="hours"><xsl:value-of select="substring-before(time, ':') mod 24" /></xsl:variable> <xsl:variable name="minutes"><xsl:value-of select="substring-after(time, ':')" /></xsl:variable> Use <xsl:if test="$days > 0"> <xsl:value-of select="$days" /> days </xsl:if> <xsl:value-of select="$hours" />:<xsl:value-of select="$minutes" /> <xsl:choose> <xsl:when test="$hours > 0"> hour<xsl:if test="$hours > 1">s</xsl:if> </xsl:when> <xsl:otherwise> minute<xsl:if test="$minute != '01:00'">s</xsl:if> </xsl:otherwise> </xsl:choose> And for clarification, a sample time would be <time>26:15:00</time> for 1 day 2:15 hours.

  • Java HashSet<Integer> to int array

    - by jackweeden
    I've got a HashSet with a bunch of (you guessed it) integers in it. I want to turn it into an array, but calling hashset.toArray(); returns an array of Object type. This is fine, but is there a better way to cast it to an array of int, other than iterating through every element manually? A method I want to pass it to void doSomething(int[] arr) Won't accept the Object[] array, even if I try casting it like doSomething((int[]) hashSet.toArray());
