A do while loop is a control flow statement that executes a block of code and then either repeats or exits depending on a condition. Learn the syntax, examples and comparison with other loop constructs in various programming languages.
Learn the difference between while loop and do while loop in programming, with examples in C++, Java, Python and C#. See the syntax, execution, initialization and update of both loops.
Do While loop Syntax in Python: Python doesn't have a built-in do while loop, but a similar behavior can be achieved using a while loop with a condition check after the code block. Syntax: while True: # Code block to be executed at least once if not condition: break Explanation of the Syntax: Python doesn't have a built-in do while loop construct.
The working of the do…while loop is explained below: When the program control first comes to the do…while loop, the body of the loop is executed first and then the test condition/expression is checked, unlike other loops where the test condition is checked first.Due to this property, the do…while loop is also called exit controlled or post-tested loop.
Do While Loop Overview. A do while loop is a control flow statement that executes a block of code at least once, and then repeatedly executes the block, or not, depending on a given boolean condition at the end of the block. [1] Some languages may use a different naming convention for this type of loop. For example, the Pascal language has a repeat until loop, which continues to run until the ...
Learn how to use the Do Until loop in Excel VBA to repeat a set of code until a condition is met. See two examples of applying the Do Until loop to fill a column with data and to check a condition.
A Do-while loop is similar to the while loop except that the condition is always executed after the body of a loop. It is also called an exit-controlled loop. In the do-while loop, the body of a loop is always executed at least once. After the body is executed, then it checks the condition. If the condition is true, then it will again execute ...
Module loops Sub Main() ' local variable definition Dim a As Integer = 10 'do loop execution Do Console.WriteLine("value of a: {0}", a) a = a + 1 Loop While (a < 20) Console.ReadLine() End Sub End Module When the above code is compiled and executed, it produces the following result −
