• A while loop is a control flow statement that allows a particular code block to be executed repeatedly based on a given condition which returns a boolean value.
• The corresponding block of code is executed continuously until the condition fails.
• The while loop can be imagined of as a repeating if statement.

     Code to execute while the condition is true
}
