Thread: Create Calculation

I'm trying to create a calculator that uses a text user interface. I have the interface writtern the way I want for now. Now I need help on writting the calculation code.

Would main() contain something like the code below?

Code:

char operation;
int quit = 0;
while(!quit)
{
    while(operation != '=')
    {
        getNumber();
        getOperation();
    }
    performCalculations();
}

Thank you
