## Algorithm

Start:

• Initialize variables for the first number (`num1`), the second number (`num2`), and the sum (`sum`).
1. Input:

• Read the first number (`num1`) from the user.
• Read the second number (`num2`) from the user.
2. Process:

• Add the values of `num1` and `num2`.
bash
```sum = num1 + num2; ```
3. Output:

• Display the sum to the user.
mathematica
```Display "The sum of num1 and num2 is: sum". ```
4. End.

This algorithm is a step-by-step description of the process of adding two numbers. When implementing this algorithm in a specific programming language, you would use the syntax of that language to perform the input, addition, and output operations.

## Code Examples

### #1 Code Example-Add of two numbers in C++ using a user-defined function

```Code - C++ Programming```

``````#include<iostream>
using namespace std;
int main()
{
int A, B, sum;
cout << "Please enter the First Number  : "<<endl;
cin >> A;
cout << "Please enter the Second Number : "<<endl;
cin >> B;
sum = A + B;
cout << "Sum of Two Numbers " << A <<" and " << B << " = " << sum;
return 0;
}``````
Copy The Code &

Output

cmd
Please enter the First Number: 10
Please enter the Second Number: 20
Sum of Two Numbers 10 and 20 = 30

### #2 Code Example- Add of two numbers in C++ using functions

```Code - C++ Programming```

``````#include<iostream>
using namespace std;

{
return x + y;
}

int main()
{
int A, B, sum;

cout << "Please enter the First Number  : "<<endl;
cin >> A;

cout << "Please enter the Second Number : "<<endl;
cin >> B;

cout << "Sum of Two Numbers " << A <<" and " << B << " = " << sum;

return 0;
}``````
Copy The Code &

Output

cmd
Please enter the First Number: 10
Please enter the Second Number: 10
Sum of Two Numbers 10 and 10 = 20

### #3 cODE eXAMPLE-Add of two numbers in C++ using recursion

```Code - C++ Programming```

``````#include<iostream>
using namespace std;

int main()
{
int A, B, sum;
cout<<"Enter Two Numbers: ";
cin>>A>>B;
cout<<"\nResult = "<<sum;
cout<<endl;
return 0;
}
{
if(b==0)
return a;
else
}
}``````
Copy The Code &

Output

cmd
Enter Two Numbers: 20 20
Result = 40
