Hello, all
My manager told me to create a large file of 2GB
The first 1GB is filled with "Hello"
and the secod 1GB is filled with "World"
Sorry to say that I don't know how to do that in an elegant way.
Does anybody know how?
Thanks for answering!
The following might do it. Don't know if it's elegant, but it's to
the point:
#include <stdio.h>
#include <stdlib.h>
int main()
{
int i;
FILE* f;
f=fopen("output","wb");
if (f==NULL) return EXIT_FAILURE;
for (i=0; i<214748364; ++i) fprintf(f,"Hello");
fprintf(f,"Hell");
for (i=0; i<214748364; ++i) fprintf(f,"World");
fprintf(f,"Worl");
if (fclose==0) return EXIT_SUCCESS;
fclose is pretty well guaranteed to not be equal to 0 ;-) fclose(f)?
return EXIT_FAILURE;
}
Dave
