Appends no more than n characters of the string pointed to by s2 (not including the termi-
nating null character) to the end of the string pointed to by s1. The initial character of s2
overwrites the null character at the end of s1. A terminating null character is always
appended to the result.

char *strncat(char *s1, const char *s2, size_t n);
Returns
The value of s1.
Example
char *ptr;
char strl[80]="Production";
char str2[]="Languages";
ptr=strncat(str1,str2,4);
strncmp
Compares no more than n characters from the string pointed to by s1 to the string pointed
to by s2.
Synopsis
#include
int strncmp(const char *s1, const char *s2, size_t n);
Returns
An integer greater than, equal to, or less than zero, according as the string pointed to by s1
is greater than, equal to, or less than the string pointed to by s2.
