Question

while input != 0
    { 
        if input == "r";
        cout << "Please input a floating point value for the height, and then a floating point value for the width, seperated by a comma." << endl;
        cin  >> height >> width;
    }

I am trying to write a basic program that takes the dimensions of basic shapes and outputs the area. This is what I am starting with, but I am not sure what is wrong with this syntax. Could someone help?

The condition must be in parentheses. Here’s your formatted code:

while (input != 0)
    { 
        if (input == "r")
        {
            cout << "Please input a floating point value for the height, and then a floating point value for the width, seperated by a comma." << endl;
            cin  >> height >> width;
        }
    }
