Challenge: Operators

In the Console.WriteLine statement, write a boolean (logical) expression which outputs true only if valueA is greater or equal to 7 and valueB is less or equal to 5.

main


              123456789101112131415
            
using System;

namespace ConsoleApp
{       
    class Program
    {
        static void Main(string[] args)
        {
            int valueA = 7;
            int valueB = 5;

            Console.WriteLine(___);
        }
    }
}

You can use the && operator to join two conditions.

main


              123456789101112131415
            
using System;

namespace ConsoleApp
{       
    class Program
    {
        static void Main(string[] args)
        {
            int valueA = 7;
            int valueB = 5;

            Console.WriteLine(valueA >= 7 && valueB <= 5);
        }
    }
}

Everything was clear?
