The purpose of this list is not to focus on remedial programming support.
You can help answer your own question by studying & playing with the
following along with studying the memset(3) manpage:
#include <stdio.h>
struct foo {
int i;
float f;
};
int main()
{
struct foo *bar[10];
printf("sizeof(struct foo) = %d\n", sizeof(struct foo));
printf("sizeof(struct foo*) = %d\n", sizeof(struct foo*));
return 0;
}
The art of programming is learned by writing lots of little programs which
answer questions like these.
