C Program to Find the Smallest Number Among Input Three Numbers

Introduction:

As a beginner in programming, learning how to write a C program to find the smallest number among input three numbers is an essential skill. This program helps you understand the fundamental concepts of conditional statements and logical operators, which are essential in programming. In this article, we will provide a step-by-step guide on how to write a C program to find the smallest number among input three numbers. By the end of this article, you will have a clear understanding of how this program works and how to implement it in your code.

Understanding the Problem

Before we start writing our C program, let's first understand the problem. We want to find the smallest number among three input numbers. To solve this problem, we need to compare the three input numbers and find the smallest one. To compare numbers in C, we use conditional statements and logical operators.

Writing the C Program

Now that we understand the problem, let's start writing our C program to find the smallest number among input three numbers. Here are the steps we need to follow:

1. Start by including the necessary header files. We will use stdio.h for input and output operations.
2. Declare three integer variables to store the input numbers.
3. Use the printf function to prompt the user to enter the three input numbers.
4. Use the scanf function to read the three input numbers and store them in the variables.
5. Compare the three input numbers using conditional statements and logical operators to find the smallest number.
6. Use the printf function to display the smallest number to the user.

Here is the code for the C program to find the smallest number among input three numbers:

Explanation:

In this program, we first declare four integer variables num1, num2, num3, and smallest. We then prompt the user to input three numbers using the printf() and scanf() functions.

We initialize the variable smallest to num1. We then use if-else statements to compare the remaining two numbers with the smallest and update their value accordingly.

The if condition checks whether num2 is the less than smallest. If it is, we update smallest to num2. Similarly, we compare num3 with smallest and update its value if it is less than the smallest.

Finally, we print the value of the smallest using the printf() function

Output:
