char * strncpy ( char * destination, const char * source, size_t num );
<cstring>
Copy characters from string
Copies the first num characters of source to destination. If the end of the source C string (which is signaled by a null-character) is found before num characters have been copied, destination is padded with zeros until a total of num characters have been written to it.No null-character is implicitly appended to the end of destination, so destination will only be null-terminated if the length of the C string in source is less than num.
