What is the difference between memcpy() and strcpy() in C?

strcpy()	memcpy()
Only for strings	For any data (int arrays, structures)
Stops at the null character	Copies exactly n bytes
Does not need a size	Needs the number of bytes

#include <stdio.h>
#include <string.h>

int main(void) {
    int a[3] = {1, 2, 3};
    int b[3];

    memcpy(b, a, sizeof(a));
    printf("%d %d %d\n", b[0], b[1], b[2]);
    return 0;
}

Output:

For overlapping memory use memmove(), because memcpy() does not handle it.
