string "equal to" don't work

[prinze]

why does s2>s1 dont work and also the "equal to", it always shows "is greater than" whenever i compile it.

#include<iostream.h>
#inlcude<conio.h>
#inlcude<string.h>
#include<stdio.h>

main()
{
clrscr();
char s1[40];
char s2[40];

cout<<"Enter 1st String:";
gets(s1);
cout<<"Enter 2nd String:";
gets(s2);

strcmp(s1,s2);

if(s1>s2)
{
cout<<s1<<" is greater  than "<<s2;
}
else if (s2>s1)
{
cout<<s2<<" is greater than "<<s1;
}
else
{
cout<<s1<<" is equal to "<<s2;
}

getch();
return 0;
}

s1 and s2 are char arrays

char s1[40];
char s2[40];

so the comparison

if(s1>s2)
{

is comparing the addresses of s1 and s2 not the contents
to compare the contents use strcmp

http://www.cplusplus.com/reference/clibrary/cstring/strcmp/

e.g.

if(strcmp(s1,s2)>0)
{
cout<<s1<<" is greater than "<<s2;
}

are you confusing C strings (arrays of char) with C++ string objects

http://www.cplusplus.com/reference/string/string/

where you can use the > == and < operators to compare string contents

It is a very bad idea to mix the C++ stream handling classes cout with the C stream handling classes gets(s1);

If you are going to use cout for output use cin for input. Alternatively use printf or puts for output.

If you are not switching to cin then DO NOT USE gets(s1); it is very unsafe as it provides no protection against buffer overwriting. use fgets(s1, sizeof s1, stdin); which prevents buffer overwriting.
