C Program to check whether input number is odd or even for SEE and NEB

 C Program to check whether the input number is odd or even for SEE and NEB

Introduction

Computer programming is a fundamental skill that is essential for students in the modern world. It not only teaches students how to solve problems but also helps them develop critical thinking skills. One of the most basic programs that students learn is how to determine whether a given number is odd or even. In this article, we will discuss how to write a C program that checks whether an input number is odd or even, specifically designed for students appearing for the SEE and NEB exams.

Program Outline

To check whether a number is odd or even, we need to divide the number by 2. If the remainder is 0, the number is even; otherwise, it is odd. Here is the outline of the program:

1. Start
2. Declare variables
3. Take input from the user
4. Check if the number is odd or even
5. Print the result
6. End

Writing the C program

C Program to Check Whether the Input Number is Odd or Even:

The program C program to check whether the input number is odd or even is a simple program that can be implemented in C language. The program takes an integer as input and checks whether it is odd or even using the modulus operator (%). If the input number is divisible by 2, then it is even, and if not, it is odd.

Here is the program:

Using if…else statement

Explanation of the Program:

The program starts by declaring an integer variable num to store the input number. Then, it prompts the user to enter an integer using the printf function and reads the input using the scanf function.

The program then checks whether the input number is even or odd using the modulus operator (%). If the input number is divisible by 2, then the remainder will be 0, and the program will print that the number is even. Otherwise, the program will print that the number is odd.

Finally, the program returns 0, indicating successful execution.

Using “if” statement

Output:

Conclusion:

In conclusion, learning how to write a program to check whether a number is odd or even is an essential concept in computer programming. It helps students understand fundamental concepts such as input/output, data types, and conditional statements. The program outlined in this article is an excellent starting point for students appearing for SEE and NEB exams. With practice and a better understanding of programming concepts, students can enhance their problem-solving skills and develop better programs in the future.

FAQs

1. What is the modulus operator?

Ans: The modulus operator (%) gives the remainder of a division operation.

2. What are some real-world applications of the concept of odd and even numbers?

Ans: The concept of odd and even numbers is used in various applications, such as in coding algorithms, cryptography, and error detection.

3. Can a decimal number be odd or even?

Ans: No, odd and even concepts only apply to integers. Decimal numbers cannot be odd or even.

4. Is it necessary to use the modulus operator to check if a number is odd or even?

Ans: No, there are other ways to check whether a number is odd or even, such as bitwise operations. However, using the modulus operator is the most straightforward and commonly used method.
