I am supposing that file is count.txt and is already exists....
so in initials of the main()
do this
*int count;
FILE* fp;
if((fp=fopen("count.txt","r"))==NULL)
{
printf("File does not exist\n");
exit(0):
}
fscanf(fp,"%d",&count);
count++;
fclose(fp);
fp=fopen("count.txt","w");
fprintf(fp,"%d",&count);
fclose(fp);
