Do-While Loop

The do-while loop is similar to the while-loop however it executes the specified code block first and then checks the condition hence it always executes the code block at least once even if the condition is false. Following is the syntax of the do-while loop:

Example:

cs

main

1234567891011121314
using System; namespace ConsoleApp { internal class Program { static void Main(string[] args) { do { Console.WriteLine("Hello World"); } while(1 < 0); } } }

The above code outputs "Hello World" even though the condition 1 < 0 is false. This will become more clear by looking at the flow diagram of the do-while loop:
