Hello, I started a few days learning C++ and I made a Console Calculator
Hope somebody find it useful, I also explained a little bit with some comments

Code:
#include <iostream>
using namespace std;
int main(void){
		double number1; // first we declare the variables number1, number2 and operation
		double number2;
		char operation;
			cout << "Insert First Number" << endl; // we ask for the first number
		cin >> number1; // here the user types the number1
			cout << "Insert Second Number" << endl; // we ask for second number
		cin >> number2; // here the user types the number2
			cout << "Insert Operation Mode" << endl; // we ask for the operation mode 
		cin >> operation; // here the user types the operation mode
	if (operation = '+'){ // if the operation mode is + then we do the next thing
			cout << "Result is " << number1 + number2 << endl; // the program makes number1+number2 and post the result
	}else if (operation = '-'){ // if the operation mode is - then we do the next thing
			cout << "Result is " << number1 - number2 << endl; // the program makes number1-number2 and post the result
	}else if (operation = '*'){ // if the operation mode is * then we do the next thing
			cout << "Result is " << number1 * number2 << endl; // the program makes number1*number2 and post the result
	}else if (operation = '/') // if the operation mode is / then we do the next thing
			cout << "Result is " << number1 / number2 << endl; // the program makes number1/number2 and post the result
	// alvaritos for MPGH
	{
	system("PAUSE"); // this is to keep the window opened!
}
