Strcmp()

[coolbran]

Hi everyone,

Can anyone tell me what is wrong with the following use of strcmp(), i know that it is supposed to return 0 if the comparison if the C-strings are equal, a Negative integer if first c-string is less than second c-string, or a positive integer if it is the other way. I always get a 1 with this:

#include <stdio.h>
#include <string.h>
#include <cstring>
#include <iostream>
using namespace std;
int main ()
{ 
 	char s1[] = "hello";
	char s2[] = "hello";
	strcmp (s1, s2) ;
	cout<<"comparison: "<<strcmp;

        return 0;
}

[Moschops]

strcmp (s1, s2)  ;
cout<<"comparison: "<<strcmp;

So you carry out the strcmp function, but you don't actually store the result anywhere, and then you attempt to cout the function strcmp.

You should be storing the result of the strcmp function you're calling, and then outputting the result.

int x = strcmp (s1, s2)  ;
cout<<"comparison: "<< x;

Oh, Duh,

I always get a 1 with this:

You always get 1 ?

cout<<"comparison: "<<strcmp;

should be displaying the address of the function strcmp()

I get

comparison: 0040131A

P.S. Note that <string.h> and <cstring> are effectively the same file. The latter just wraps the former in the std namespace.
