Cpp program to Addition Subtraction,Multiplication and division

Cpp program to Addition Subtraction, Multiplication and division

In this tutorial, we will discuss Cpp program to Addition Subtraction, Multiplication and division

 

In this post, we will learn how to perform addition, subtraction multiplication, division of any two numbers  using if else statements in Cpp programming

The  program will request the user to enter two number digits and the user select an operator to perform the addition, subtraction, multiplication, and division of the entered number by the user and displays the output on the screen
the program will display the result according to the user selection

Program 1

#include <iostream>
#include <conio.h>

using namespace std;

int main()
{
    int num1,num2;
    cout << "Enter two numbers" << endl;
    cin>>num1>>num2;
    cout<<"\nAddition of"<<num1<<"+"<<num2<<" = "<<num1+num2;
    cout<<"\nSubtraction of"<<num1<<"-"<<num2<<" = "<<num1-num2;
    cout<<"\nMultiplication of"<<num1<<"*"<<num2<<" = "<<num1*num2;
    cout<<"\nDivision of"<<num1<<"/"<<num2<<" = "<<num1/num2;
    getch();
    return 0;
}

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

Enter two numbers
100
20

Addition of 100+20 = 120
Subtraction of 100-20 = 80
Multiplication of 100*20 = 2000
Division of 100/20 = 5

 

Program 2

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

int main()
{
    char ch;
    int num1,num2;
cout<<"Enter the first number: ";
cin>>num1;
cout<<"Enter the second number: ";
cin>>num2;
cout<<"Enter the operator you want(+, -, x, /) :";
cin>>ch;
if(ch=='+'){
    cout<<"Addition is :" <<num1+num2;
}
else if(ch=='-'){
    cout<<"Subtraction is :"<<num1-num2;
}

else if(ch=='+'){
    cout<<"Multiplication is :"<<num1*num2;
}

else if(ch=='+'){
    cout<<"Division is :"<<num1/num2;
}

else{
    cout<<"This operator not in use";
}

getch();
return 0;
}

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

Case 1

Enter the first number: 60
Enter the second number: 10
Enter the operator you want(+, -, x, /):+
Addition is: 70

 

Case 2

Enter the first number: 60
Enter the second number: 10
Enter the operator you want(+, -, x, /):-
Subtraction is: 50

 

Case 3

Enter the first number: 100
Enter the second number: 10
Enter the operator you want(+, -, x, /):*
Multiplication is: 1000

 

Case 4

Enter the first number: 60
Enter the second number: 10
Enter the operator you want(+, -, x, /):/
Division is: 6

Case 5

Enter the first number: 60
Enter the second number: 10
Enter the operator you want(+, -, x, /):x
This operator not in use
