strncmp function — Compares strings
int strncmp(const char* s1, const char* s2, size_t n)
The strncmp
function
compares at most n
characters of
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.
