strcmp function — Compares strings
int strcmp(const char* s1, const char* s2)
The strcmp
function
compares two null-terminated strings as arrays of unsigned
char
. If the strings are equal, the return
value is 0
. Otherwise, the return
value is positive if s1
is
greater than s2
or negative if
s1
is less than s2
. If one string is a prefix of the
other, the longer string is greater than the shorter string.
