# 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:

• 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

1. Use `Convert.ToInt32()` and `Convert.ToString()`.
``````
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
}
}
}
``````
