Thread: Program Error has me stuck

I'm a beginner with C++ and am writing a program that calculates whether a triangle is right, valid or invalid. On the coding for a right triangle i'm struggling( i figured this would be the easy part) If someone could help with this portion it would be greatly appreciated! Thanks

Code:

 int main()
{
    int a, b, c;
    cout << "Please input three values for leg lengths: ";
    cin >> a >> b >> c;
    cin.ignore();
    if ( a + b > c) {
        cout << "That is not a valid triangle." << endl;
    }
    else if ( a*a + b*b = c*c) {
        cout << "That's a right triangle." << endl;
    }
    cin.get();
}

Error occurs in the else if statement saying non-1value in assignment?

Again thanks in advance for any and all help!

figured it out...stupid mistake thanks anyways
