Find largest and smallest number in an array in C#

Find largest and smallest number in an array in C#

To find the largest and smallest number in an array in C#, you can use the Max and Min methods from LINQ or implement a simple loop to iterate through the array and keep track of the maximum and minimum values. Here are both approaches:

  • Using LINQ's Max and Min methods:
using System; using System.Linq; public class Program { public static void Main() { int[] numbers = { 10, 5, 20, 15, 30 }; // Find the largest number using LINQ Max int largestNumber = numbers.Max(); // Find the smallest number using LINQ Min int smallestNumber = numbers.Min(); Console.WriteLine($"Largest number: {largestNumber}"); Console.WriteLine($"Smallest number: {smallestNumber}"); } }
  • Using a simple loop:
using System; public class Program { public static void Main() { int[] numbers = { 10, 5, 20, 15, 30 }; // Find the largest and smallest numbers using a loop int largestNumber = numbers[0]; int smallestNumber = numbers[0]; for (int i = 1; i < numbers.Length; i++) { if (numbers[i] > largestNumber) { largestNumber = numbers[i]; } if (numbers[i] < smallestNumber) { smallestNumber = numbers[i]; } } Console.WriteLine($"Largest number: {largestNumber}"); Console.WriteLine($"Smallest number: {smallestNumber}"); } }

Both approaches will give you the same result:

Largest number: 30 Smallest number: 5

You can choose the approach that suits your code style and requirements. The LINQ approach is more concise and expressive, while the loop approach might be preferred in performance-critical scenarios as it requires only a single pass through the array.
