Calculator

[ofiryak1994]

Hey guys, been trying to make myself a calculator and ran into some trouble lol,
if you guys can spot the problem i'd be thankful :)

#include <iostream>
#include <cmath>

using namespace std;

int main()
{
//fen: first entered number. sen:second entered number. ma:mathematical action

double fen, sen, ma;
double a, b, c, d;
//a - sum outcome. b - difference outcome c - multipication outcome d - division outcome

a = fen + sen;
b = fen - sen;
c = fen*sen;
d = fen / sen;

cout << "Welcome to the world finest calculator\n";
cout << "Please enter the mathematical calculation you want to perform, using + for sum, - for difference, * for multipication and / for division\n";
cin >> fen >> ma >> sen;

if (ma = +)
cout << "The sum of the numbers is:" << a << endl;
if (ma = -)
cout << "The difference of the two numbers is:" << b << endl;
if (ma = *)
cout << "The multipication of the two numbers is:" << c << endl;
if (ma = / )
cout << "The division of the two numbers is:" << d << endl;

cout << "Thank you for using the world best calculator" << endl;


return 0;

Yeah, there are plenty of problems. This is obvious :

if (ma = +)
cout << "The sum of the numbers is:" << a << endl;
if (ma = -)
cout << "The difference of the two numbers is:" << b << endl;
if (ma = *)
cout << "The multipication of the two numbers is:" << c << endl;
if (ma = / )
cout << "The division of the two numbers is:" << d << endl;

Yeah ok, just changed it into this:

if (ma = '+')
		cout << "The sum of the numbers is:" << a << endl;
	if (ma = '-')
		cout << "The difference of the two numbers is:" << b << endl;
	if (ma = '*')
		cout << "The multipication of the two numbers is:" << c << endl;
	if (ma = '/' )
		cout << "The division of the two numbers is:" << d << endl;

and it still wont work, says it cant identify "fen" and "sen".
