C++ Program to Add Two Numbers.

Adding two numbers in C++ programming is a very basic beginner-level question and one can easily write the code by following the below instructions.

Instruction:

Declare two integer-type variables num1 and num2.
Take two integer-type input variables from the user which we are going to store in num1 and num2.
Declare another integer-type variable sum and initialize the variable with 0.
Add two variables num1 and num2 and store the answer in the sum variable.
Print the value present in the sum variable.

C++ Code to Add Two Integer Type Numbers.

#include<iostream>
using namespace std;

int main(){

    int num1, num2;
    
    cout<<"Enter the first number: ";
    cin>>num1;
    
    cout<<"\nEnter the second number: ";
    cin>>num2;

    int sum = 0;
    sum = num1 + num2;
    //Print sum 
    cout<<"Sum of two numbers: "<<sum;
    
    return 0;
}

Output:

Enter the first number: 10
Enter the second number: 5
Sum of two numbers: 15

Note: For this example, we are using an integer-type variable but you can change your change the data type of your variables based on the requirement like you can use float-type variables to add decimal values.(alert-success)

C++ Code to Add Two Float Type Numbers.

#include<iostream>
using namespace std;

int main(){

    float num1, num2;
    
    cout<<"Enter the first number: ";
    cin>>num1;
    
    cout<<"\nEnter the second number: ";
    cin>>num2;

    float sum = 0;
    sum = num1 + num2;
    //Print sum 
    cout<<"Sum of two numbers: "<<sum;
    
    return 0;
}

Output:

Enter the first number: 3.4
Enter the second number: 5.3
Sum of two numbers: 8.7
