first checks whether x is less than 5, which it is, so then the {loop body} is entered, where the printf function is run and x is incremented by 1. After completing all the statements in the loop body, the condition, (x < 5), is checked again, and the loop is executed again, this process repeating until the variable x has the value 5.
Do while loops check the condition after the block of code is executed. This control structure can be known as a post-test loop. This means the do-while loop is an exit-condition loop. However a while loop will test the condition before the code within the block is executed.
The while loop below will execute the code in the loop 5 times. x is initialized to 0, and each time in the loop the value of x is incremented. The while loop is set up to stop when x is equal to 5.
For example, a loop that iterates five times (from 0 to 4 inclusive) can be written as a half-open interval from 0 to 5: for ( index = 0 ; index < 5 ; index ++ ) { /* Body of the loop */ } The loop body is executed first of all with index equal to 0; index then becomes 1, 2, 3, and finally 4 on successive iterations.
In many programming languages, only integers can be reliably used in a count-controlled loop. Floating-point numbers are represented imprecisely due to hardware constraints, so a loop such as. for X := 0.1 step 0.1 to 1.0 do. might be repeated 9 or 10 times, depending on rounding errors and/or the hardware and/or the compiler version.
Fentanyl from Canada represents 0.2% of total U.S. seizures of fentanyl, Canada’s Energy and Natural Resources Minister Jonathan Wilkinson said. About the same amount of fentanyl was seized by ...
If in the 'addition' program above the second loop decrements x 0 instead of incrementing, the program computes the difference (cut off at 0) of the variables and . x 0 := x 1 LOOP x 2 DO x 0 := x 0 ∸ 1 END. Like before we can extend the LOOP syntax with the statement: x 0 := x 1 ∸ x 2
