Thread: file handling in C

hii everyone..
could anyone help me out with file handling in c.actually i wanted to know the command for reading the contents of a file from our computer.i mean we generally give a name to the file but if we want to retrieve the contents of a file from our system is it possible in c language?
thanx and regards,

You have to open the file using fopen(), then you can use any of the f* input functions to read from it. Search this forum for fopen() and you'll find lots of sample code.

http://www.cppreference.com/
that's a good list of some of the commonly used C and C++ libraries and the functions in them.

http://www.cppreference.com/stdio/index.html
From that same list, here's the IO functions for C, including file functions

to open a binary file for reading,

Code:

#include <stdio.h>

int main(int argc, char **argv) {
  FILE *f;
  char buf[BUFSIZ];
  int bs;
  f = fopen("file.bin","rb"); //use r for Read, w for Write, and b for Binary
  bs = fread(buf,1,BUFSIZ,f); //buffer, entry size (char = 1), entry count, file
  fclose(f);
  return 0;
}

actually i want a text file content to be displayed in the command prompt..when i try giving the path like c:\a.txt..it says file not found..

Backslash starts an escape sequence. Try using either "C:\\a.txt" or "C:/a.txt".

thanx a lot..i got it..:d
