Statement 1 sets a variable before the loop starts (int i = 0). Statement 2 defines the condition for the loop to run (i must be less than 5). If the condition is true, the loop will start over again, if it is false, the loop will end. Statement 3 increases a value (i) each time the code block in the loop has been executed. Time of my life song. Syntax for ( for-range-declaration: expression ) statement Remarks. Use the range-based for statement to construct loops that must execute through a 'range', which is defined as anything that you can iterate through—for example, std::vector, or any other C Standard Library sequence whose range is defined by a begin and end.
Unlike for and while loops, which test the loop condition at the top of the loop, the do..while loop checks its condition at the bottom of the loop.
A do..while loop is similar to a while loop, except that a do..while loop is guaranteed to execute at least one time.
Syntax
The syntax of a do..while loop in C++ is −

Notice that the conditional expression appears at the end of the loop, so the statement(s) in the loop execute once before the condition is tested.

If the condition is true, the flow of control jumps back up to do, and the statement(s) in the loop execute again. This process repeats until the given condition becomes false.
