CAN YOU PLEASE HELP ME WITH THIS CODE. AND PLEASE GIVE SOME EXPLNATION.

#include <iostream>

using std::cout;

using std::cin;

using std::endl;

int main()

{

            int input;

            cout<< " Please enter an integer: ";

            cin >> input;

            if (input != 7)

                        cout << " Hello "<<endl;

            if (input == 7)

                        cout << " Goodbye" << endl;                                       

                        system("PAUSE");

            return 0;

}

Assume that the user enters 5 for input

PART II: Programming

4. Write a C++ program that inputs two integers from the keyboard, and prints the sum,   product, difference, and quotient of these numbers

Explanation / Answer

Hi,

Please find the solution for your question.

#include<iostream>
using namespace std;

int main()
{
int firstNumber, secondNumber, sumOfTwoNumbers,productOfTwoNumbers,differenceOfTwoNumbers,divisionOfTwoNumbers;

//prints on screen to prompt user to enter the numbers
cout<<"Enter Two Integers:";  

// inputs numbers from user and stores them in integers a and b
cin>>firstNumber>> secondNumber;

// sum of two numbers in stored in variable sumOfTwoNumbers
sumOfTwoNumbers = firstNumber + secondNumber;

// product of two numbers in stored in variable productOfTwoNumbers
productOfTwoNumbers = firstNumber * secondNumber;

// difference of two numbers in stored in variable differenceOfTwoNumbers
differenceOfTwoNumbers = firstNumber - secondNumber;

// division of two numbers in stored in variable divisionOfTwoNumbers
divisionOfTwoNumbers = firstNumber / secondNumber;

cout<<"Sum: "<<firstNumber << "+" << secondNumber << "=" << sumOfTwoNumbers << endl;
cout<<"Product: "<<firstNumber << "*" << secondNumber << "=" << productOfTwoNumbers << endl ;
cout<<"Difference: "<<firstNumber << "-" << secondNumber << "=" << differenceOfTwoNumbers << endl;
cout<<"Quotient: "<<firstNumber << "/" << secondNumber << "=" << divisionOfTwoNumbers << endl;
return 0;
}

Output:

Enter Two Integers: 4 2

Sum : 4+2 = 6

Product : 4*2 = 8

Difference : 4-2 = 2

Quotient: 4/2 = 2
