I finished the new calculator

I figured out how to make it so the user could imput the signs instead of having to put 2 numbers seperated by a space.

Can you tell me waht you guys think?

Code:#include <iostream> using namespace std; double add (double a, double b)//Addition Function { return (a + b); } double subtract (double c, double d)//Subtraction Function { return (c - d); } double multiply (double e, double f)//Multiplication Function { return (e * f); } double divide (double g, double h)//Division Function { return (g / h); } int main () { double pick1, pick2; char choose, method; cout << "*********************" << endl; cout << "***The Calculator****" << endl; cout << "**By : Ryan Nielson**" << endl; cout << "*********************\n\n" << endl; do { cout << "\n\nPlease type your question below. Use + to add, - to subtract," << endl; cout << "* to multiply or / to divide.\n " << endl; cin >> pick1 >> method >> pick2; if (method == '+')//addition cout << "\n" <<pick1 << method << pick2 << "=" << add (pick1, pick2) << endl; else if (method == '-')//substraction cout << "\n" <<pick1 << method << pick2 << "=" << subtract (pick1, pick2) << endl; else if (method == '*')//multiply cout << "\n" <<pick1 << method << pick2 << "=" << multiply (pick1, pick2) << endl; else if (method == '/')//divide cout << "\n" <<pick1 << method << pick2 << "=" << divide (pick1, pick2) << endl; else cout << "\nIncorrect input!!!!!" << endl; cout << "\nWould you like to [c]ontinue or [e]xit: "; cin >> choose; }while ((choose != 'e') && (choose != 'E')); return 0; }
