Basic Coding Practice

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:

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

  2. Add 2 to the value of temp.

  3. Convert the value of temp to a string and assign it to the variable num

cs

main

copy
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().

cs

main

copy
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 } } }

Everything was clear?

How can we improve it?
