DESCRIPTION
The arguments 81, 82 and 8 point to strings (arrays of characters
terminated by a null character). The functions 8trcat, 8trncat,
8trcpy and 8trncpy all alter 81 . These functions do not check for
overflow of the array pointed to by 81 .
Strcat appends a copy of string 82 to the end of string 81 .
Strncat appends at most n characters. Each returns a pointer to
the null-terminated result.
Strcmp compares its arguments and returns an integer less than,
equal to, or greater than 0, according as s1 is lexicographically less
than, equal to, or greater than s2. Strncmp makes the same comparison
but looks at n characters at most.
