Sample Program Output

Program Listing

divide.cpp

#include <iostream>

using namespace std;

int main() { 

int dividend=0, divisor=0;

// Get two integers from the user 

cout << "Divisor Program in C++";

cout << "\n\n";

cout << "Please enter two integers to divide:"; 

cin >> dividend >> divisor; 

// If possible, divide them and report the result 

if (divisor != 0) {

cout <<"\n\n";

cout << dividend << "/" << divisor << " = " << dividend/divisor << '\n'; 

}

else {

cout <<"\n\n";

cout << "Division by zero is not allowed\n";

}

cout <<"\n\n";

cout << "End of Program";

Prompt JavaScript Calculator

In this article I would like to show you how to create a prompt JavaScript calculator. Our program is very simple it will ask the user to give the first value, the second is the operator  addition, subtraction, multiplication and division and then the second value. Our program will display the result on the screen using if else statement in JavaScript.
