What did I do wrong?

[kinkita]

Hello everyone!
I've just started with c and I think it's really fun! even though I can't do much... I have previous knowledge in a program language called GML, it's not an advanced language, it's about as hard as Javascript.

Anyway I tried to make a fairly short program in c :

#include <iostream>
#include <string>
using namespace std;

int main ()
{
    int  yes ;
    string name;

    cout << "Stranger: Hello";
    cout << "Stranger: What's your name?";
    cout <<"\n\nThe stranger who you just met wants to know your name, what should you do?\n\n";
    cout <<"type in 1 if you want to tell the stranger your name\nor 0 if you want to run away from that maniac.";

    cin >> yes;







        if (yes = 1){
        cout << "You decide to tell the stranger your name...";
        cout << "Stranger: What is your name?";
        cin >> name;
        cout << name <<":" << " My name is " <<name <<".";
        cout << "Okey, It was niec meating you..." << name;

    }

if (yes = 0)
    {
        cout << "You ran away\n";
        cout << "blablabla";
        cout << "blablablabla";




    }




    return 0;
}

The following code would probably work in GML with just a few fixes but in c it seems as if the programm ignore the "if (yes=0)" statment. What did I do wrong? and also what should I do to be able to get a string from the player, for example

if (yes = "yes")

Thanks in advance! :)

'=' is assignment. if (yes = 0) means "assign 0 to yes, and then check the result for truthiness". The result is 0, which is implicitly converted to false, so the "if-part" is never executed. Comparisons for equality are done with "==". As for the second question, just change these two lines:

intstring yes ;

if (yes = 1 == "yes")

The language is called C++ by the way. C is a different language.

First of all you should decide for yourself what language you are using. Because what you showed is not the C.
Secondly, this (in bold)

if (yes = 1){

is not a comparision. It is an assignment. So the expression will be always equal to true because it is not equal to zero.

Please excuse my mistake. The language I'm trying to code in is c++ but I must have forgotten the plusses(facepalm) Anyhow, thanks for the enlightenments :) it made things much clearer now.
