Subtract two numbers in C++ programming

Subtract two numbers in C++ programming

In this article, we will discuss the concept of the Subtract two numbers in C++ programming

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

Subtract two integer numbers

The program use to find subtraction of given two integer numbers

Program 1

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

int main()
{
    int num1=366,num2=189;
    //variable declaration

    int sub=num2-num1;
    //formula of subtraction

    cout<<"Differences of two numbers are: "<<sub;
    //display the result
    getch();
    return 0;
}

 

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

Differences of two numbers are: -177

 

Subtract two integer numbers using user input

This program allows the user to enter two integer numbers Then the program find the subtraction of the given two number

Program 2

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


int main()
{
    int num1,num2;
    //variable declaration

    cout<<"Enter two integer for subtract: ";
    cin>>num1>>num2;//read the inputs

    int sub=num2-num1;
    //formula of subtraction

    cout<<"Differences between two numbers are: "<<sub;
    //display the result
    getch();
    return 0;
}

When the above code isexecuted, it produces the following result

case 1

Enter two integer for subtract: 456
567
Differences between two numbers are:111

 

case 2

Enter two integer for subtract: 567
456
Differences between two numbers are:-111

 

Subtract two float numbers

The program use to find subtraction of given two float numbers

Program 3

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


int main()
{
    float num1=544.567,num2=767.324;
    //variable declaration and initialization
    float sub=num2-num1;
    //formula of subtraction

    cout<<"Differences between two numbers are: "<<sub;
    //display the result
    getch();
    return 0;
}

When the above code isexecuted, it produces the following result

Differences between two numbers are:222.757

 

Subtract two float numbers using user input

This program allows the user to enter two float numbers Then the program find the subtraction of the given two number

Program 4

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


int main()
{
    float num1,num2;
    //variable declaration and initialization

    cout<<"Enter two float numbers: ";
    cin>>num1>>num2;//read the inputs

    float sub=num2-num1;
    //formula of subtraction

    cout<<"Differences of two numbers are: "<<sub;
    //display the result
    getch();
    return 0;
}

When the above code isexecuted, it produces the following result

case 1

Enter two float numbers: 123.456
234.567
Differences between two numbers are:111.111

 

case 2

Enter two float numbers : 234.567
123.456
Differences between two numbers are:-111.111
