Answer to Question #155182 in C++ for zain ul abdeen

Question

Write a program which takes two integers (num1 and num2) as input from the user.

Your program should display on the screen the result of i) num1 + num2, ii) num1 * num2, and iii) num1 - num2.

You are not allowed to use the + or - or * operators. E.g., cout<<num1+num1<<num1*num2<<num1-num2; is not allowed. += or -= or *= operators are also not allowed.

You HAVE TO USE loops and the ++ and -- operators. Code for num1+num2 is already available in the slides. Use that for this assignment.

Answer 1

#include "stdafx.h"
#include <iostream>
using namespace std;


int main()
{
	int num1, num2;
	int a,b,c,d;
	a = 0;
	b = 0;
	c = 0;
	d = 0;
	cout << "Enter Num1..." << endl;
	cin >> num1;
	cout << "Enter Num2..." << endl;
	cin >> num2;
	while (a < num1)
		a++;
	while (b < num2)
	{
		a++;
		b++;
	}
	cout <<"1)The amount = "<< a << endl;
	for (int i = 0; i < num1; i++)
		for (int j = 0; j < num2; j++)
			d++;
		cout << "2)The product = " << d << endl;
	if (num1>num2)
	{
		b = num1;
		a = num2;
		while (a != b)
		{
			c++;
			b--;
		}
	}
	else
	{
		b = num2;
		a = num1;
		while (a != b)
		{
			c++;
			b--;
		}
	}
	cout << "3)The difference = " << c << endl;
	system("Pause");
	return 0;
}
