calculator problems

count4zero (4)
I just started to make my way in c++ and i'm trying to build a calculator.
everything is working fine except my "if" and "else" in case 4. it would be nice if anyone could help me and explain what i did wrong.

(i didn't include all my lines so it would be more clean)

switch(userChoice)
{  
case '4':
    cout << "enter number you want to divide " << X << " by" <<endl;
    cin >> Y;
    cout << " " << endl;
    if(Y = 0) {cout << "ERROR";
    }
    else
    {cout << "the result is " << (X / Y);
    }
    break;

if(Y = 0) What is the difference between = and ==?

I searched for many things but i didn't find a way for this. how can I make it work so i can start from the top if they choose Y after my last cout
