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
