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 calculate the subtraction of two numbers with out using minus operator in C programming language

Code to calculate 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 <stdio.h>
#include <stdlib.h>

int main()
{
    int num1=100,num2=20,sub;
    //Variable declaration
    sub=num1+~num2+1;
    //find subtraction without minus
    printf("Subtraction of %d and %d is: %d",num1,num2,sub);
    //display the output
    getch();
    return 0;
}

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

Subtraction of %d and %d is: %d

Subtract two integer without using minus operator – Takes input from user

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

Program 2

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int num1,num2,sub;
    printf("Enter the first number ");
    //ask input from the user
    scanf("%d",&num1);
    //store the input number in num1
      printf("Enter the second number ");
    //ask input from the user
    scanf("%d",&num2);
    //store the input number in num1
    sub=num1+~num2+1;
    //find subtraction without minus
    printf("Subtraction of %d and %d is: %d",num1,num2,sub);
    //display the output
    getch();
    return 0;
}

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

Enter the first number 25
Enter the second number 5
Subtraction of 25 and 5 is: 20

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 to store variable num1
Using scanf() function to store the first input value in num1
Request the user to enter second input to store variable num2
Using scanf() function to store the second input value in num2
find the subtraction of num1 and num2 without using minus operator
Finally, display result on the screen- the subtraction of both numbers num1 and num2
