This program runs perfect just want to know if I have to do this arithmetic operations using functions how can I do that?

``````// Arithmetic.cpp - This program performs arithmetic, ( +. -, *. / ) on two numbers.
// Input:  Interactive
// Output:  Result of arithmetic operation

#include <cstdlib>
#include <iostream>
#include <string>

using namespace std;
int main(int argc, char *argv[])
{
double numberOne, numberTwo;
string operation;
double result;

cout << "Enter the first number: ";
cin >> numberOne;
cout << "Enter the second number: ";
cin >> numberTwo;
cout << "Enter an operator (+.-.*,/): ";
cin >> operation;

if (operation == "+")
{
result = numberOne + numberTwo;
}
else if (operation == "-")
{
result = numberOne - numberTwo;
}
else if (operation == "*")
{
result = numberOne * numberTwo;
}
else if (operation == "/")
{
result = numberOne / numberTwo;
}

cout << numberOne;
cout << " " << operation << " ";
cout << numberTwo;
cout << " = ";
cout << result << endl;

system("PAUSE");
return EXIT_SUCCESS;
} // End of main() function``````

Wait.....what?

What do you mean? You want to do what in functions? Call a separate function to read in the input and a function to perform the math? A separate function for each arithmetic operation? You only want to have variable declarations and function calls in your main()?

Just create some functions, for example a function for addition would
look like this :

``````int addNumbers(int number1, int number2){
return number1 + number2;
}``````

And you can do similar for other operation.

It might seem like its not worth it but doing this will make your program
neater and better.
