Thread: improve program.

Hey can some of you tell me some way to make my program better? some tips or something, thanks.

Code:

#include <stdio.h>
#include <stdlib.h>


int main (void)
{
	int opencount = 0;
   char ligne[1000];
   char * buff;
   long num;

   FILE *dataIn = NULL;

   dataIn = fopen("c:\\time.txt", "r");
    if ( dataIn == NULL )
	  {
        perror("something went wrong\n" );
        return EXIT_FAILURE;
	  }

	while(fgets(ligne, sizeof(ligne), dataIn) !=NULL)
	  opencount++;


   printf("You rebooted your comp %d times.\n\n", opencount);


   fseek (dataIn , 0 , SEEK_END);
   num = ftell (dataIn);
   rewind (dataIn);

   buff = (char*) malloc (num);
     if (buff == NULL)
       exit (EXIT_FAILURE);

   fread (buff,1,num,dataIn);
   printf("%s", buff);
	fclose(dataIn);
	free (buff);


   return EXIT_SUCCESS;
}

thanks all

ronin, what im trying to do is read from the file that this prog creates

Code:

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

int main()
{

	FILE * pFile;
   time_t now;
   time(&now);

	pFile = fopen ("c:\\time.txt","at");
   fputs (ctime(&now), pFile);
   fclose(pFile);

   return EXIT_SUCCESS;
}

i put this in the start up folder and everytime the computer boots up it writes to the file saying what time and date it started. Then with the other code i posted i read from that file and it tells me how many time i rebooted the computer and at what time and date. anyway thanks for all the info ronin and vVv. I'll do the modifications.

LOL. I think someone is cheating. What, you didn't know I had an account here also?

I have seen your name a few times. But I guess I can allow that. Since I want to know what they say to make it better
