Lab 1 Smallest Numberwrite A Program Whose Inputs Are Three Integers

Introduction

Determining the smallest number among a set of integers is a fundamental programming task often used to introduce basic control structures, variable comparisons, and input/output operations. This paper presents a comprehensive solution to identify the smallest among three integers provided by the user, using Python as the programming language for clarity and simplicity. The program emphasizes user interaction, conditional logic, and output formatting to achieve the desired functionality effectively.

Methodology

The approach involves prompting the user to input three integer values, storing these inputs in variables, and then utilizing comparison operators to determine the smallest number. The algorithm compares each number with the others to find the minimum. The implementation ensures robust input handling and clear output presentation.

Implementation

The Python code demonstrates the process step by step:

Prompt the user for three integers


num1 = int(input("Enter the first integer: "))


num2 = int(input("Enter the second integer: "))


num3 = int(input("Enter the third integer: "))


Determine the smallest of the three


smallest = num1


if num2 

smallest = num2


if num3 

smallest = num3


Output the smallest number


print("The smallest of the three numbers is:", smallest)

The code initializes the variable smallest with the first input and then checks subsequent inputs to update the variable if a smaller number is found. This process ensures that ultimately, smallest holds the minimum of all three inputs.

Conclusion

The presented program effectively addresses the problem of identifying the smallest number among three integers. It highlights fundamental programming concepts such as input handling, conditional statements, and output formatting. This solution can be extended or integrated into larger applications requiring minimum value computations.
