C++ Example to subtract two integer without using minus operator

In this article, we will discuss the concept of the C++ Example to subtract two integer without using minus operator

In this post, we are going to learn how to write a program to find the subtraction of two numbers using with out using minus operator in C++ programming language

Code to find the subtraction of two numbers

Subtract two integer without using minus

The program use to calculate subtraction of given two integer numbers without using minus operator in C++ language

Program 1

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    int num1=200,num2=65,sub;
    //Variable declaration
    sub=num1+~num2+1;
    //find subtraction without minus
    cout<<"Subtraction of "<<num1<< " and "<<num2<<" is: "<<sub;
    //display the output
    getch();
    return 0;
}

When the above code is executed, it produces the following result

Subtraction of 200 and 65 is: 135

Subtract two integer without using minus – Takes input from user

The program allow the user to enter two numbers and then calculates subtraction of given two integer numbers without using minus operator in C++ language

Program 2

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    int num1,num2,sub;
    cout<<"Enter the value for num1"<<endl;
    //ask input from user for num1
    cin>>num1;
    //string the value in num1
    cout<<"Enter the value for num2"<<endl;
    //ask input from user for num2
    cin>>num2;
    //string the value in num2
    sub=num1+~num2+1;
    //find subtraction without minus
    cout<<"Subtraction of "<<num1<< " and "<<num2<<" is: "<<sub;
    //display the output
    getch();
    return 0;
}

When the above code is executed, it produces the following result

Enter the value for num1
500
Enter the value for num2
150
Subtraction of 500 and 150 is: 350

Methods

Create two variables to store two numbers as input provided by the user: num1,num2;
Create a variable to store the subtraction of these numbers: sub
Request the user to enter first input for store variable num1
Using cin>> store the first input value in num1
Request the user to enter second input for store variable num2
Using cin>> store the second input value in num2
find the subtraction of num1,num2 without using minus operator
Finally, display result on the screen- the subtraction of both numbers num1 and num2
