While loop is counted as pretested loop.
The difference is that pre means before and post means after in Latin so it's tested before or after. :)
A counted loop is a loop that executes the loop's statement a pre-determined number of times. The count represent the exit condition of the loop. A loop that is not counted is an infinite loop.
Pretest loops, such as for-loop, while-loop, execute/evaluate the condition statement first, if the condition is met, then the statements of the loop are executed. If you were referring to the body of the loop being carried out at least once, no, the body will not be touched if the condition fails (pre-test, test BEFORE the [next] execution of the body). But the condition of the loop must have been evaluated at least once.In contrast to the post-test loops, such as do-while, repeat-until, the condition is evaluated AFTER the [next] execution of the body. It is possible that the condition is never evaluate, and not the entire loop body being executed.
Well, from my knowledge of pseudocode, a pre-test loop contains the DO WHILE and LOOP functions. So say you want to pour some milk into your cereal for breakfast: DO WHILE cereal_bowl.Full = False Pour_Milk LOOP Basically this is you saying, I am going to pour milk WHILE the bowl is not full. Once the bowl is full you will stop because you checked before your poured (a pre-test). Hope this helps. - The Doctor
A counted loop. Typically we use a for loop for counted loops: // loop 10 times... for (int i=0; i<10; ++i) { // ... } We can also use while and do-while loops to do the same thing, however a for loop provides all the information up front where it belongs and we can localise the control variable. With while and do-while loops, the control variable must be declared outside the loop, and the increment is usually specified at the end of the loop. This makes while and do-while loops harder to read because the information that controls the loop is separated: // loop 10 times... int i = 0; while (i<10) { // ... ++i; } A do-while loop is similar to a while loop, but the control expression is placed at the end of the loop thus the loop always executes at least once. This also upsets the logic of a counted loop because the control variable is off-by-one. // loop 10 times... int i = 0; do { // ... ++i; } while (i<11);

A for loop is typically used to implement a counted loop: for x=0 to 100 step 1 print x next x
Use a counted for loop: int x;for (x=1; x<=100; ++x) { /* ... */ }
pretest means a practice test

anais montes lopes medina is asking what does pretset means do you under stand can you help me please and thank you very much it is hard to be smart be cause im so little in my life and family please anwser
The utility of HLA-B27 teating depends on the pretest probability of disease.
I did well on the test because I did all the recommended pretest questions.
