#include <cstring> int strncmp( const char *str1, const char *str2, size_t count );
The strncmp() function compares at most count characters of str1 and str2. The return value is as follows:
|less than 0||
|equal to 0||
|greater than 0||
If there are less than count characters in either string, then the comparison will stop after the first null termination is encountered.
