# Describe about do-while loop.

[Briefly explain](https://www.mindstick.com/forum/156854/briefly-explain-the-concept-of-constructor-overloading) me about do-while loop with its example.

Do-While statement is used to execute the block of statement until the condition is true.

It is similar to while loop but the only difference is that, in **[while loop the block of statement](https://www.mindstick.com/forum/155714/define-while-loop)** will execute only when the condition is true, but in do-while statement will execute at least once, because the body of statement will execute first then the condition is checked.

We use keyword do and while to create the body for do-while loop.

## Syntax

```
do
{
    //statement of body to execute
}while(condition);
```

## Example

```
using System;
namespace Do_While
 {
    class Program
    {
        static void Main(string[] args)
        {
            int i = 1;
            do
            {
                Console.WriteLine("i value: {0}", i);
                i++;
            } while (i <= 4);
            Console.WriteLine("Press Enter Key to Exit..");
            Console.ReadLine();
        }
    }
}
```

## Output:-

```
i value: 1 i value: 2
i value: 3
i value: 4
Press Enter Key to Exit..
```
