I need to write a Windows XP/Vista application, main requirements:
Just one .exe file, without extra runtime, like Air, .Net; posstibly a couple of dlls.
Very small file size.
The application is for network centric usage, similar to ICQ or Gtalk clients.
I have a system where a central Java controller launches analysis processes, which may be written in C++, Java, or Python (mostly they are C++). All these processes currently run on the same server. What are you suggestions to
Create a central log to which all processes can write to
What if in the future I push some processes to another server. How can I support distributed logging?
Thanks!
Hello,
I am practice the function in c and come across to the program ....
include
int main()
{
float a=15.5;
char ch ='C';
printit(a,ch);
return 0;
}
printit(a,ch)
{
printf("%f\n%c",a,ch);
}
I want to know that why the above program compile and not give the error as i understood so for is ...
1) The function in c must be declared with the specific prototype (but this program does not contain the prototype )
2)why the program give the output 'x'for the char variable
3)can the function in c are capable of accepting the value without being declared about type in parameters like what has done in the function declaration ....
plz.... help
Apparently Apple has changed some term in the agreement again.
From http://www.appleoutsider.com/2010/06/10/hello-lua/
section 3.3.2 is now
Unless otherwise approved by Apple in writing, no interpreted code may be downloaded or used in an Application except for code that is interpreted and run by Apple’s Documented APIs and built-in interpreter(s). Notwithstanding the foregoing, with Apple’s prior written consent, an Application may use embedded interpreted code in a limited way if such use is solely for providing minor features or functionality that are consistent with the intended and advertised purpose of the Application.
instead of the original

I am more interested in embedding Lua, but other people have other embeddings they want to make.
I am wondering how you ask for permission, and what they mean by the terms "minor features" and "consistent" and how will Apple interpret this section? It seems to have enough loopholes to drive a real firetruck through.

(BTW this is a terribly important question for me an my product.)
Hey guys, had a basic doubt. What exactly is so totally different about languages like php that they are called scripting languages and languages like c are called normal programming languages?
How do I make sure I've got a double and not something else?
int main() {
int flagOk = 0;
double number;
while(!flagOk) {
printf("Put in a double");
scanf("%lf", &number);
if(number == "%lf"); //this want make sure
flagOk = 1;
}
}
Hi,
How can i copy multiple char* variables into one char* at single instance operation.
say i have
char* text1 = "Hello";
char* text2 = "World";
i want to copy text1, text2 and '2' and "12345" into char* text3 in single function call.
Hi again, here is my coding which gives me the error 'warning: unknown conversion type character 0x20 in format'
int subtotal;
long long a,b,c,d,e,f,g,h,i,j,k,l,m;
subtotal = (1*(a+c+e+g+i+k))+(3*(b+d+f+h+j+l));
printf(" = %d % 10 = %d; (10 - %d) % 10 = %lld\n", subtotal,subtotal%10,subtotal%10,m);
any idea why this is wrong?
I am reading source code of hoard memory allocator, and in the file of gnuwrapper.cpp, there are the following code
#define CUSTOM_MALLOC(x) CUSTOM_PREFIX(malloc)(x)
What's the meaning of CUSTOM_PREFIX(malloc)(x)? is CUSTOM_PREFIX a function? But as a function it didn't defined anywhere. If it's variable, then how can we use variable like var(malloc)(x)?
more code:
#ifndef __GNUC__
#error "This file requires the GNU compiler."
#endif
#include <string.h>
#include <stdlib.h>
#include <stdio.h>
#include <malloc.h>
#ifndef CUSTOM_PREFIX ==> here looks like it's a variable, so if it doesn't define, then define here.
#define CUSTOM_PREFIX
#endif
#define CUSTOM_MALLOC(x) CUSTOM_PREFIX(malloc)(x) ===> what's the meaning of this?
#define CUSTOM_FREE(x) CUSTOM_PREFIX(free)(x)
#define CUSTOM_REALLOC(x,y) CUSTOM_PREFIX(realloc)(x,y)
#define CUSTOM_MEMALIGN(x,y) CUSTOM_PREFIX(memalign)(x,y)
Hi,
I am searching a character at first occurence in string using the following code.
But, it is taking some time when the character is too long or the character that i am
searching is at far extend, which makes delay in other operations. How could i tackle with
this problem. The code is below here.
Note: attrPtr is a char* which holds a reference to a string containing '"' character at
far extend.
int position = 0;
char qolon = '"';//character to search
while (*(attrPtr + position++) != qolon);
char* attrValue = NULL;
attrValue = (char*)malloc(position * sizeof(char));
strncpy(attrValue, attrPtr, position-1);
this is the question--
Write a program to manipulate the temperature details as given below.
- Input the number of days to be calculated. – Main function
- Input temperature in Celsius – input function
- Convert the temperature from Celsius to Fahrenheit.- Separate function
- find the average temperature in Fahrenheit.
how can I make this program without initial size of array ??
#include<stdio.h>
#include<conio.h>
void input(int);
int temp[10];
int d;
void main()
{
int x=0;
float avg=0,t=0;
printf("\nHow many days : ");
scanf("%d",&d);
input(d);
conv();
for(x=0;x<d;x++)
{
t=t+temp[x];
}
avg=t/d;
printf("Avarage is %f",avg);
getch();
}
void input(int d)
{
int x=0;
for(x=0;x<d;x++)
{
printf("Input temperature in Celsius for #%d day",x+1);
scanf("%d",&temp[x]);
}
}
void conv()
{
int x=0;
for(x=0;x<d;x++)
{
temp[x]=1.8*temp[x]+32;
}
}
Hi,
I can store string of few length in char data type.
But when it exceeds its capacity what can be the alternative way to store string.
I am using char data type.
void setString(char* inPoints)
{
if (strcmp(mPoints, inPoints)!= ZERO) {
if (mPoints) {
free(mPoints);
}
mPoints = (char*)malloc((strlen(inPoints) + 1) * sizeof(char));
strcpy(mPoints, inPoints);
}
}
Say there is a file called 12345.jpg. In C, how can I get the file extension so that I can compare with some file extension? If there are any inbuilt functions, kindly please let me know.
Hi,
Is it the correct way of allocating memory to a char*.
char* sides ="5";
char* tempSides;
tempSides = (char*)malloc(strlen(inSides) * sizeof(char));
Hi
I am java professional since last one year. I am pretty familier with core java and JSP and SERVLET technologies.Now I am hired by a telcom company where java is not used.The question I like to ask here is how to keep java enviornment around me so that I should not be unfamiler with java.
As I come from company I get much time to work with java.
I like to know any real time projects in java available so that I can work with java also.
Please let me know...
Thanks in advance
I've been researching programming languages, in hopes of learning to program.
Since I've heard a lot of good things about Ruby, I went ahead and purchased The Pragmatic guide to Ruby.
I understand that there is a lot of hype about Ruby on Rails.
Because ruby lets you program scripts, applications, and internet helped me to decide on learning Ruby vs other languages.
Today I watched a talk about google go, and it's really caught my attention.
Coincidently I stumbled on a talk about jruby.
I've been under the impression that java applications are bloated an slow.
However the speaker made a point of what is wrong with Ruby, and how Jruby diagnosed Ruby's shortcomings.
All that said. I would like to hear peoples opinions on Jruby vs Ruby, and if Ruby is working on fixing these "short comings".
Also, how do you, the programming community feel about "go" and if I'm making a mistake learning Ruby instead of go, or Jruby.
Appreciate your advice and opinions
Thanks,
Some of our friends (University students) are trying to develop a twitter type application, I want to plan for at least 1000 transactions per second (I know it's wishful thinking) for initial launch. This involves several people connecting and getting updates and posting (text + images) to site. In the back end db will server the data and also calculates rankings of what to push to user based on complex algorithm on the fly real-time.
Our group is familiar with Java and Tomcat/MySQL. We can also easily learn/code in PHP/MySQL. What is the best suited platform for our purpose ?
Though Java seem to be easy to implement for us I am afraid that hosting will be a bit difficult. I could find cloud based php hosting services (like rackspace cloudsites) at reasonable cost. Amazon EC2 is a bit over our heads to manage on day-to-day.
Also any recommendation on hosting ? (PHP or Java) We don't have millions in seed money but about $20K to start with.
Any advice on above or any thing in general approach is much appreciated.
