Help with a noob code

[jahkrohn]

Ok me and my friends wanna make this simple program, to give us some expirence to make more, but to start we wanna make this one that disses one of our last names.
can you tell me why when we enter coss it says thats a cool last name instead of he is a homo.

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

int main()

{
    char string[50];

printf("Enter your last name...\n");
fgets(string, 50, stdin);
    if(string=="coss") {
        printf("you're homo\n");
    }
    else {
        printf("That's a cool last name\n");
    }

    return 0;
}

please help, I just started C a month ago so im not to skilled at all

use strcmp function to compare strings

[jahkrohn]

where do we put strcmp in the code ?

[vart]

char a[] = "test";
const char* b = "test2";
if(strcmp(a,b) == 0)
{
   puts("match");
}
else
{
   puts("failed");
}

if(string=="coss") {
    printf("you're homo\n");
}

A little background on what's happening here and why this doesn't work...

"coss" is what's called a string literal. The characters making up this are stored in the program's data segment somewhere at some specific address. The variable string is an array of characters that exist on the stack at some other specific address. In the above context, you basically asking "if the address of the variable string is equal to the address of the string-literal "coss" then print the message". If you think this through, the two objects here, the literal and the variable string, will never have the same address in memory, they are distinct objects. What you want to have happen here, and what the strcmp function does, is compare the values that are stored at those two different addresses and see if those contents are similar.
