Largest and Lowest of Three Integers

Write a C# program to find the largest and lowest values from three integer values.

C# Sharp Exercises: Find the largest and lowest values from three integer values

Sample Solution:

C# Sharp Code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

public class Exercise39 {
    static void Main(string[] args) {
        // Prompt the user to input the first integer
        Console.WriteLine("\nInput first integer:");

        // Read the input and convert it to an integer 'x'
        int x = Convert.ToInt32(Console.ReadLine());

        // Prompt the user to input the second integer
        Console.WriteLine("Input second integer:");

        // Read the input and convert it to an integer 'y'
        int y = Convert.ToInt32(Console.ReadLine());

        // Prompt the user to input the third integer
        Console.WriteLine("Input third integer:");

        // Read the input and convert it to an integer 'z'
        int z = Convert.ToInt32(Console.ReadLine());

        // Find and display the largest of the three integers using Math.Max method
        Console.WriteLine("Largest of three: " + Math.Max(x, Math.Max(y, z)));

        // Find and display the smallest of the three integers using Math.Min method
        Console.WriteLine("Lowest of three: " + Math.Min(x, Math.Min(y, z)));
    }
}

Sample Output:

Input first integer:                                                   
15                                                                     
Input second integer:                                                  
25                                                                     
Input third integer:                                                   
30                                                                     
Largest of three: 30                                                   
Lowest of three: 15
