std::strcat

From cppreference.com
Defined in header <cstring>
char *strcat( char *dest, const char *src );

Appends a byte string pointed to by src to a byte string pointed to by dest. The resulting byte string is null-terminated.

The destination byte string must have enough space for the contents of both dest and src, plus the terminating null character.

The behavior is undefined if the strings overlap.
