Thread: My first cpp app

Well at least the basics are really similar to Java. I just need to think of things to do. :dunno:

Code:

// Calc.cpp
// CompiledMonkey

#include "stdafx.h"

void add()
{
	float x, y;

	std::cout << "Enter first number: ";
	std::cin >> x;

	std::cout << "Enter second number: ";
	std::cin >> y;

	std::cout << x << " + " << y << " = " << (x + y) << "\n";
}

void subtract()
{
	float x, y;

	std::cout << "Enter first number: ";
	std::cin >> x;

	std::cout << "Enter second number: ";
	std::cin >> y;

	std::cout << x << " - " << y << " = " << (x - y) << "\n";
}

int main()
{
	bool flag = true;
	int option = 0;

	do
	{
		// Display menu and get option
		std::cout << "\n1: Add\n2: Subtract\n3: Exit\n\nPick an operation: ";
		std::cin >> option;

		switch(option)
		{
			case 1:
				add();
				break;
			case 2:
				subtract();
				break;
			case 3:
				flag = false;
				break;
			default:
				std::cout << "Bad choice!\n\n";
				break;
		}
	}
	while(flag);

	return 0;
}
