strcat


function
<cstring>
char * strcat ( char * destination, const char * source );

Concatenate strings

Appends a copy of the source string to the destination string. The terminating null character in destination is overwritten by the first character of source, and a new null-character is appended at the end of the new string formed by the concatenation of both in destination.

Parameters

destination
Pointer to the destination array, which should contain a C string, and be large enough to contain the concatenated resulting string.
source
C string to be appended. This should not overlap destination.


Return Value

destination is returned.
