Challenge: if Condition

Write an if-condition which checks if the variable x is in the range of 40 to 70 (including 40 and 70). Use the <= operators for comparison. If the condition is true, it should output "In Range".

cs

main

copy

              
12345678910111213141516

            
using System;

namespace ConsoleApp
{       
    class Program
    {
        static void Main(string[] args)
        {
            int x = 55;

            // Write code below this line

            // Write code above this line
        }
    }
}

The syntax of an if-condition is: if(condition) { /* code to execute */ }

cs

main

copy

              
1234567891011121314151617181920

            
using System;

namespace ConsoleApp
{
    class Program
    {
        static void Main(string[] args)
        {
            int x = 55;

            // Write code below this line
            if (40 <= x && x <= 70)
            {
                Console.WriteLine("In Range");
            }
            // Write code above this line

        }
    }
}

Var alt klart?

Hvordan kan vi forbedre det?
