    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; }

  • Log call information whenever there is a phone call.

    - by linuxdoniv
    Hi, I have written the android application and I want the application to send the call information whenever there is an incoming call and it ends. This way I would be sending all calls to the server irrespective of size of the call log. Here is the code public class PhoneInfo extends BroadcastReceiver { private int incoming_call = 0; private Cursor c; Context context; public void onReceive(Context con, Intent intent) { c = con.getContentResolver().query( android.provider.CallLog.Calls.CONTENT_URI, null, null, null, android.provider.CallLog.Calls.DATE+ " DESC");

  • What is an XYZ-complete problem?

    - by TheMachineCharmer
    EDIT: Diagram: http://www.cs.umass.edu/~immerman/complexity_theory.html There must be some meaning to the word "complete" its used every now and then. Look at the diagram. I tried reading previous posts about NP- My question is what does the word "COMPLETE" mean? Why is it there? What is its significance? N- Non-deterministic - makes sense' P- Polynomial - makes sense but the "COMPLETE" is still a mystery for me.

  • iphone cocos2d sprites disappearing

    - by jer
    I've been working on a game and implementing the physics stuff with chipmunk. All was going fine on the cocos2d part until the integration with chipmunk. A bit of background: The game is a game with blocks. Levels are defined in a property list, where positions, size of the blocks, gravitational forces, etc., are all defined for each block to be shown in the level. The problem is with the blocks showing up. I have a method on my BlockLayer class which is part of my game's main scene. Upon creation of the layer, the property list is read, and all the blocks are created. The following method is called to create the blocks: - (void)createBlock:(Block*)block withAssets:(NSBundle*)assets { Sprite* sprite; switch(block.blockColour) { case kBlockColourGreen: sprite = [Sprite spriteWithFile:[assets pathForResource:@"green" ofType:@"png" inDirectory:@"Blocks"]]; break; case kBlockColourOrange: sprite = [Sprite spriteWithFile:[assets pathForResource:@"orange" ofType:@"png" inDirectory:@"Blocks"]]; break; case kBlockColourRed: sprite = [Sprite spriteWithFile:[assets pathForResource:@"red" ofType:@"png" inDirectory:@"Blocks"]]; break; case kBlockColourBlue: sprite = [Sprite spriteWithFile:[assets pathForResource:@"blue" ofType:@"png" inDirectory:@"Blocks"]]; break; } sprite.position = block.bounds.origin; [self addChild:sprite]; if(block.blockColour == kBlockColourGreen || block.blockColour == kBlockColourRed) space-gravity = cpvmult(cpv(0, 10), 1000); cpVect verts[] = { cpv(-block.bounds.size.width, -block.bounds.size.height), cpv(-block.bounds.size.width, block.bounds.size.height), cpv(block.bounds.size.width, block.bounds.size.height), cpv(block.bounds.size.width, -block.bounds.size.height) }; cpBody* blockBody = cpBodyNew([block.mass floatValue], INFINITY); blockBody-p = cpv(block.bounds.origin.x, block.bounds.origin.y); blockBody-v = cpvzero; cpSpaceAddBody(space, blockBody); cpShape* blockShape = cpPolyShapeNew(blockBody, 4, verts, cpvzero); blockShape-e = 0.9f; blockShape-u = 0.9f; blockShape-data = sprite; cpSpaceAddShape(space, blockShape); } With the above code, the sprites never show up. However, if I comment out the "cpSpaceAddBody(space, blockBody);" line, the sprites show up. The position and size of the blocks are stored in the "bounds" property of instances of the Block class, which is a CGRect. Not sure if it's important, but the orientation of the app is in landscape left, and all the coordinates are based on that orientation. Any help would be greatly appreciated.

  • How do I get fine-grained undo in Vim

    - by MDCore
    I find Vim's undo to be a bit too coarse. E.g. if I type something like this: a // to go into edit mode to be or not to ve <esc> // to exit insert mode Oops! I made a typo. I want to start undoing so I press u, but then it clears the whole line. Is there a way to undo word-by-word or character-by-character?

  • How can I load a file into a DataBag from within a Yahoo PigLatin UDF?

    - by Cervo
    I have a Pig program where I am trying to compute the minimum center between two bags. In order for it to work, I found I need to COGROUP the bags into a single dataset. The entire operation takes a long time. I want to either open one of the bags from disk within the UDF, or to be able to pass another relation into the UDF without needing to COGROUP...... Code: # **** Load files for iteration **** register myudfs.jar; wordcounts = LOAD 'input/wordcounts.txt' USING PigStorage('\t') AS (PatentNumber:chararray, word:chararray, frequency:double); centerassignments = load 'input/centerassignments/part-*' USING PigStorage('\t') AS (PatentNumber: chararray, oldCenter: chararray, newCenter: chararray); kcenters = LOAD 'input/kcenters/part-*' USING PigStorage('\t') AS (CenterID:chararray, word:chararray, frequency:double); kcentersa1 = CROSS centerassignments, kcenters; kcentersa = FOREACH kcentersa1 GENERATE centerassignments::PatentNumber as PatentNumber, kcenters::CenterID as CenterID, kcenters::word as word, kcenters::frequency as frequency; #***** Assign to nearest k-mean ******* assignpre1 = COGROUP wordcounts by PatentNumber, kcentersa by PatentNumber; assignwork2 = FOREACH assignpre1 GENERATE group as PatentNumber, myudfs.kmeans(wordcounts, kcentersa) as CenterID; basically my issue is that for each patent I need to pass the sub relations (wordcounts, kcenters). In order to do this, I do a cross and then a COGROUP by PatentNumber in order to get the set PatentNumber, {wordcounts}, {kcenters}. If I could figure a way to pass a relation or open up the centers from within the UDF, then I could just GROUP wordcounts by PatentNumber and run myudfs.kmeans(wordcount) which is hopefully much faster without the CROSS/COGROUP. This is an expensive operation. Currently this takes about 20 minutes and appears to tack the CPU/RAM. I was thinking it might be more efficient without the CROSS. I'm not sure it will be faster, so I'd like to experiment. Anyway it looks like calling the Loading functions from within Pig needs a PigContext object which I don't get from an evalfunc. And to use the hadoop file system, I need some initial objects as well, which I don't see how to get. So my question is how can I open a file from the hadoop file system from within a PIG UDF? I also run the UDF via main for debugging. So I need to load from the normal filesystem when in debug mode. Another better idea would be if there was a way to pass a relation into a UDF without needing to CROSS/COGROUP. This would be ideal, particularly if the relation resides in memory.. ie being able to do myudfs.kmeans(wordcounts, kcenters) without needing the CROSS/COGROUP with kcenters... But the basic idea is to trade IO for RAM/CPU cycles. Anyway any help will be much appreciated, the PIG UDFs aren't super well documented beyond the most simple ones, even in the UDF manual.

  • Insight into how things get printed onto the screen (cout,printf) and origin of really complex stuff

    - by sil3nt
    I've always wondered this, and still haven't found the answer. Whenever we use "cout" or "printf" how exactly is that printed on the screen?. How does the text come out as it does...(probably quite a vague question here, ill work with whatever you give me.). So basically how are those functions made?..is it assembly?, if so where does that begin?. This brings on more questions like how on earth have they made openGl/directx functions.. break it down people break it down.:)

  • Add UIView and UILabel to UICollectionViewCell. Then Segue based on clicked cell index

  • Compose synthetic English phrase that would contain 160 bits of recoverable information

    - by Alexander Gladysh
    I have 160 bits of random data. Just for fun, I want to generate pseudo-English phrase to "store" this information in. I want to be able to recover this information from the phrase. Note: This is not a security question, I don't care if someone else will be able to recover the information or even detect that it is there or not. Criteria for better phrases, from most important to the least: Short Unique Natural-looking The current approach, suggested here: Take three lists of 1024 nouns, verbs and adjectives each (picking most popular ones). Generate a phrase by the following pattern, reading 20 bits for each word: Noun verb adjective verb, Noun verb adjective verb, Noun verb adjective verb, Noun verb adjective verb. Now, this seems to be a good approach, but the phrase is a bit too long and a bit too dull. I have found a corpus of words here (Part of Speech Database). After some ad-hoc filtering, I calculated that this corpus contains, approximately 50690 usable adjectives 123585 nouns 15301 verbs This allows me to use up to 16 bits per adjective (actually 16.9, but I can't figure how to use fractional bits) 15 bits per noun 13 bits per verb For noun-verb-adjective-verb pattern this gives 57 bits per "sentence" in phrase. This means that, if I'll use all words I can get from this corpus, I can generate three sentences instead of four (160 / 57 ˜ 2.8). Noun verb adjective verb, Noun verb adjective verb, Noun verb adjective verb. Still a bit too long and dull. Any hints how can I improve it? What I see that I can try: Try to compress my data somehow before encoding. But since the data is completely random, only some phrases would be shorter (and, I guess, not by much). Improve phrase pattern, so it would look better. Use several patterns, using the first word in phrase to somehow indicate for future decoding which pattern was used. (For example, use the last letter or even the length of the word.) Pick pattern according to the first bytes of the data. ...I'm not that good with English to come up with better phrase patterns. Any suggestions? Use more linguistics in the pattern. Different tenses etc. ...I guess, I would need much better word corpus than I have now for that. Any hints where can I get a suitable one?
