Modulo Operator and If-Clause

[Dink]

Hi,
I'm a Beginner in C++ and I have a problem with the Modulo operator.

I'm writing a testprogram with following sourcecode:

#include <iostream>
using namespace std;

int main ()
{
    //Definition Variablen

    int d, e, erg;
    
    cout<<"Zahl 1 eingeben: \n";
    cin>>e;
    cout<<"Zahl 2 eingeben: \n";
    cin>>d;
    
    if (erg = e % d == 0)
    {
        cout<<"Der Rest ist 0 \n";    
    }

    else
    
    {
        cout<<"Der Rest ist: "<<erg<<endl;
    }
    
    
    system ("Pause");
    return 0;
}

After starting the program I have to type in the two numbers.
Then it should compare if the rest = 0.
Then it should say "Rest is 0" or "Rest is erg"

But whatever I type in the both variables, everytime the output is "Rest is 0".
Can anybody tell me what is my mistake?


Best regards

if (erg = e % d == 0) doesn't do what you want. You can fix your code in this way:

...
if ((erg = e % d )== 0)
...

or

...
erg=e%d;
if (erg == 0)
...

Thanks it's working ;-)
