Case1: If length of str2 > n then it just copies first n characters of str2 into str1. Case2: If length of str2 < n then it copies all the characters of str2 into str1 and appends several terminator chars('\0') to accumulate the length of str1 to make it n. #include <stdio.h> #include <string.h> int main() { char first[30] = "Happy Codings"; char second[30] = "C Programming Language Code Examples: I'm using strncpy now"; /* this function has copied first 10 chars of s2 into s1*/ strncpy(s1,s2, 12); printf("String s1 is: %s", s1); return 0; }
