Answer to Question #155178 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 <iostream>


using namespace std;


int main()
{
	int num1, num2;
	cin >> num1 >> num2;
	int a = num1;
	for (int i = 0; i < num2; i++)
		a++;
	int b = 0;
	for (int i = 0; i < num1; i++)
		for (int j = 0; j < num2; j++)
			b++;


	int c = num1;
	for (int i = 0; i < num2; i++)
		c--;
	cout << a << endl;
	cout << b << endl;
	cout << c << endl;
}
