strcmp
Description:
Include:
Prototype:
Arguments:
Return Value:
Remarks:
Example:
Compares two strings.
<string.h>
int strcmp(const char *s1, const char *s2);
s1
s2
Returns a positive number if s1 is greater than s2, zero if s1 is equal to
s2, or a negative number if s1 is less than s2.
This function compares successive characters from s1 and s2 until
they are not equal or the null terminator is reached.
