strncpy()

A more secure version of strcpy() which requires you to provide the # of bytes to be copied.

Note: do not copy more than the length of the string. it will override the ‘\0’ null terminator

#include <stdio.h>
#include <string.h>
 
int main(){
    char str1[] = "HI MAN";
    char str2[7];
 
    strncpy(str2, str1, 6); // do not go over the length of str2
}
