Hi all I'm trying to write a program that counts all the characters in a string. I originally had it, but then realized I can't count spaces. I can't see why this does not work. for(m=0; z[m] != 0; m++) { if(z[m] != ' ') { charcount ++; } } Any assistance appreciated. Edit* Does it make a difference if the input(str...

I'm interested in writing a Gtk application that uses an embedded SVG canvas for graphics, and I'm wondering what the current state-of-the-art is for using SVG in Gtk. I know that it's possible to embed Webkit inside of Gtk, and so that seems like one approach, but I would like to add interactivity to DOM elements in the embedded SVG can...

static char yes[80]; int main(int argc, char *argv[]) { void (*point)(); // ... sets yes[] = to input point = (void*) yes; (*point)(); } so does this create a function and execute commands that are in yes[]? how does it know to read the commands in yes? do i type in c, or does it have to be assembly? ...
I'm trying to run this code on Windows 7 (64-bit, if it matters) after compiling it with GCC. If I declare bufsize as an int, the program freezes and Windows informs me that it's stopped working. If I use #define bufsize 123 it works fine, and it works fine if I replace bufsize with a number myself. What am I missing here? int mai...
I have two arrays of chars, allocated as follows: unsigned char *arr1 = (unsigned char *)malloc((1024*1024) * sizeof(char)); unsigned char *arr2 = (unsigned char *)malloc((768*768) * sizeof(char)); I would like to copy arr2 into arr1, but preserve the row/column structure. This means that only the first 768 bytes of each of the fir...
What i would love to do is to create a function that takes a parameter that is the limit of which number the random generation should create. I have experienced that some generators that just repeat the number generated over and over again. How can I make a generator that doesn't return the same number consecutively. Can someone please...
Hi, I want to read the contents of a text file into a char array in C. Newlines must be kept. How do I accomplish this? I've found some C++ solutions on the web, but no C only solution. Thanks! Yvan Edit: I have the following code now: void *loadfile(char *file, int *size) { FILE *fp; long lSize; char *buffer; fp =...
I worked on this yesterday about 5 hours and got the code to work using help from this site, but I think the way I did it was a cheater way, I used a scanf command. Anyways I want to fix this the correct way. Thanks guys! Oh the code compiles but the average that gets spit out is wrong. I would like to conceptually understand what I ...
Hi, I'm trying to compile this program under Windows (it's a program which turns bootable code in floppies. I got the source from here: http://www.acm.uiuc.edu/sigops/roll_your_own/1.bootstrap.html). First I got the problem that it didn't read the INI file. That is solved now. Now I get a segfault on the following rule: while(data < e...

I'm trying to send data to an SD card from a PIC18f4580, but the PIC is not sending what it should be. related global variables: unsigned char TXBuffer[128]; //tx buffer unsigned char TXCurrentPos = 0x00; //tracks the next byte to be sent unsigned char TXEndPos = 0x00; //tracks where new data should be put into the array I am adding ...
Hi, I am totally stumped. I have a fairly large recursive program written in c that calls cblas_dgemm(). The result is verified independently by a program that works correctly. C = alpha*A*B + beta*C On repeated tests using random matrices and all possible combination of parameters the program gives correct answer ONLY if abs(beta) ...

I want a function that reads in a file and returns the sum of ascii values.

How can I crack two ciphertexts that have used the same key twice? For example, plaintext1 uses the key "abcdefg", and plaintext2 uses the key "abcdefg". I know that ciphertext2 ^ ciphertext1 is equal to plaintext1 ^ plaintext2. And the method to crack plaintext1 ^ plaintext2 is the same method to crack a "book cipher" (also sometimes c...
