C# program to find the maximum and minimum number between two numbers

Here, we are asking for two integer numbers, finding the maximum and minimum and maximum number using if-else statement and the ternary operator.

// C# program to read two numbers 
// and find maximum, minimum number

using System;
using System.IO;
using System.Text;

namespace IncludeHelp {
  class Test {
    // Main Method 
    static void Main(string[] args) {
      int a;
      int b;
      int min;
      int max;

      //input numbers
      Console.Write("Enter first number : ");
      a = Convert.ToInt32(Console.ReadLine());
      Console.Write("Enter second number: ");
      b = Convert.ToInt32(Console.ReadLine());

      //finding max number using if-else
      if (a > b)
        max = a;
      else
        max = b;

      //finding min number using if else
      if (a < b)
        min = a;
      else
        min = b;

      //printing
      Console.WriteLine("Using if-else...");
      Console.WriteLine("Minimum number = {0}", min);
      Console.WriteLine("Maximum number = {0}", max);

      //finding max number using ternary operator
      max = (a > b) ? a : b;

      //finding min number using ternary operator
      min = (a < b) ? a : b;

      //printing
      Console.WriteLine("Using Ternary operator...");
      Console.WriteLine("Minimum number = {0}", min);
      Console.WriteLine("Maximum number = {0}", max);

      //hit ENTER to exit the program
      Console.ReadLine();
    }
  }
}

Output

Enter first number : 100
Enter second number: 200
Using if-else...
Minimum number = 100
Maximum number = 200
Using Ternary operator...
Minimum number = 100
Maximum number = 200
