you need a cin for x and a cin for y.

you will need a switch statement - so go back to the tutorials for switch().

when you are done you will have

double add( double x, double y ) { ... }
double sub( double x, double y ) { ... }
double mult( double x, double y ) { ... }
double div( double x, double y ) { ... }

don't forget to check for dividing by zero.

remember - when all else fails, google on calculator c++ !!!!!!!!!

@bdlt
Who do you have to make things sound so hard

@lilhawk2892
here is a simple calculator to add two numbers

#include <iostream>
using namespace std;

int main()
{
double a;
double b;
double total;
cout<<"Enter first number" << endl;
cin >> a;
cin.ignore();

cout<<"Enter second number" << endl
cin >> b;
cin.ignore();

total = a + b;
cout<<"The total of " a  " + "  b "  is  " total << endl;
cin.get();
return 0;
}

18 C:\Dev-Cpp\main.cpp expected `;' before string constant


can u pls fix it i really dont know where to put it

the compiler found a problem with line 18.

18 C:\Dev-Cpp\main.cpp expected `;' before string constant

look carefully at line 18

cout<<"Enter second number" << endl

do you see anything missing?
