Efficient C Program to Add Two Numbers

Introduction:

In this article, we will discuss how to write an efficient C program to add two numbers. Adding two numbers is a fundamental operation in programming and is often used in various applications. By following the steps outlined below, you will be able to create a simple yet optimized program that adds two numbers together.

1. Understanding the Problem
2. Approach and Algorithm
3. Implementing the C Program
4. Testing the Program
5. Conclusion
6. Understanding the Problem: Before we dive into the code, let’s have a clear understanding of the problem. We are given two numbers, and our task is to write a C program that adds these numbers and displays the sum as output.
7. Approach and Algorithm: To solve this problem, we can use a straightforward approach. We will take input from the user for the two numbers, add them together, and display the sum as output. Here’s the algorithmic representation of our approach:a. Start b. Declare variables: num1, num2, sum c. Read the values of num1 and num2 from the user d. Add num1 and num2, and store the result in sum e. Display the value of sum f. End
8. Implementing the C Program: Let’s now implement the algorithm in the form of a C program:
#include<stdio.h> int main() { int a, b, sum; printf(“\nEnter two no: “); scanf(“%d %d”, &amp;a, &amp;b); sum = a + b; printf(“Sum : %d”, sum); return(0); }

## Out Put

```Enter two no: 5 6
Sum : 11
```

Conclusion:

In this article, we have successfully implemented an efficient C program to add two numbers. We learned about the problem, devised an algorithm, and implemented the solution using C programming. By following the steps described above, you can now create your own C programs to add numbers or even extend this program to perform additional calculations.

Remember, this program serves as a basic foundation for more complex programs, and understanding the core concept of adding two numbers is crucial when learning any programming language.

Happy coding!
