Do-While LoopDo-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.cs

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:

How many iterations will the following loop have?
