using Assembly language C Starting with the windows32 projec

using Assembly language C++

Starting with the windows32 project located in Figure 3.11, modify the example program and already in the project. Prompt for, input and add three numbers, and display the sum.

Use the sub mnemonic to subtract another input value from the sum calculated in the problem stated above. Display the result.

Solution

#include <iostream>

int main()

{

      int number1;

       int number2;

       int number3;

       int sum;

     std::cout << \"Enter first number: \"; // prompt user for data

     std::cin >> number1;

     std::cout << \"Enter second number: \"; // prompt user for data

     std::cin >> number2;

      std::cout << \"Enter second number: \"; // prompt user for data

     std::cin >> number3;

     sum = number1 + number2 + number3; // add the numbers; store result in sum

     std::cout << \"Sum is \" << sum << std::endl; // display sum;
