Learn Challenge: Variable Declaration

Complete the code by declaring the variables value_1 and value_2 having values 10 and 20 respectively.

Note

You can combine strings and numbers in C# output using the + operator. When you use + between a string and a number, C# automatically converts the number to its string form and joins them together. For example, "Result: " + 5 will output Result: 5.

main.cs


              12345678910111213141516
            
namespace ConsoleApp
{
    internal class Program
    {
        static void Main(string[] args)
        {
            // Write code below this line
            
            // Write code above this line


            System.Console.WriteLine("Value 1: " + value_1);
            System.Console.WriteLine("Value 2: " + value_2);
        }
    }
}

Use the var keyword and the assignment operator (=) for variable declaration.

main.cs


              1234567891011121314151617
            
namespace ConsoleApp
{
    internal class Program
    {
        static void Main(string[] args)
        {
            // Write code below this line
            var value_1 = 10;
            var value_2 = 20;
            // Write code above this line


            System.Console.WriteLine("Value 1: " + value_1);
            System.Console.WriteLine("Value 2: " + value_2);
        }
    }
}
