Question

Write a C++ program that performs the four arithmetic operations (addition, subtraction, multiplication and division) on two numbers received from keyboard by prompting. Your program must have specific function for each arithmetic operation. 

Answer 1

#include <iostream>


using namespace std;


double executeAddition(double number1, double number2)
{
    return number1+number2;
}


double executeSubtraction(double number1, double number2)
{
    return number1-number2;
}


double executeMultiplication(double number1, double number2)
{
    return number1*number2;
}


double executeDivision(double number1, double number2)
{
    return number1/number2;
}


int main()
{
    cout << "Enter first number: ";
    double number1;
    cin >> number1;


    cout << "Enter second number: ";
    double number2;
    cin >> number2;


    cout << endl;


    cout << number1 << " + " << number2 << " = " << executeAddition(number1, number2) << endl;
    cout << number1 << " - " << number2 << " = " << executeSubtraction(number1, number2) << endl;
    cout << number1 << " * " << number2 << " = " << executeMultiplication(number1, number2) << endl;


    if(number2!=0)
        cout << number1 << " / " << number2 << " = " << executeDivision(number1, number2) << endl;
    else
        cout << "Unable to execute division" << endl;


    cout << endl << endl;


    return 0;
}
