A number is stored in a variable called num in the form of a string. Add 2 to the stored number. You may use the following steps:

Convert the value of num string to an integer and store it in a new integer variable called temp.
Add 2 to the value of temp.
Convert the value of temp to a string and assign it to the variable num

main.cs


              123456789101112131415161718
            
using System;

namespace ConsoleApp
{
    internal class Program
    {
        static void Main(string[] args)
        {
            string num = "15";

            // Write code below this line

            // Write code above this line

            Console.WriteLine(num); // Expected Output: 17
        }
    }
}

Use Convert.ToInt32() and Convert.ToString().

main.cs


              1234567891011121314151617181920
            
using System;

namespace ConsoleApp
{
    internal class Program
    {
        static void Main(string[] args)
        {
            string num = "15";

            // Write code below this line
            int temp = Convert.ToInt32(num);
            temp = temp + 2;
            num = Convert.ToString(temp);
            // Write code above this line

            Console.WriteLine(num); // Expected Output: 17
        }
    }
}
