Is a while loop a pre-condition or post condition?
The while loop is a pre-condition loop. It tests the condition at the beginning of each loop, executes the loop if it is true, and goes back to the test after executing each iteration.
Is the for loop a pretest type of 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.
What are the components of loop?
a loop consist of data initialization;test condition;updation; example a for loop for(int a=1;a<5;a++) the loop will be executed 5 times four positives result and the last test condition will be failed and the loop will be exited there are many loops some of them are while loop,do...while loop,for loop,maybe more...... do while is an exit check loop and while and for are entry check loop.
What the difference between pretest loop and posttest loops?
The difference is that pre means before and post means after in Latin so it's tested before or after. :)
What three features does a loop decision point consist of?
A loop decision point consists of an initial value, a test condition and a set of actions to be performed. In a Java for loop, this is written as for (i = 0 (initial value); i < someValue (test condition); i++ (action performed)).
Is a while loop a pre-condition or post condition?
The while loop is a pre-condition loop. It tests the condition at the beginning of each loop, executes the loop if it is true, and goes back to the test after executing each iteration.
What are the 3 differences between for and while loop?
For Loop:1.In this first it initialized with the starting value such as I=0,count=0.The value which was initialized is then checked with the given test condition. While Loop:1.In this it checks the condition first. for Loop:2.In this we initializ,check conition and increment or dicrement in one statement While loop2:In this only we can test the condition in one statements. For Loop3:general Format: for (initialization; test condition; increment) { body of the loop } While loop:3.general Format while(test condition) { body of the loop }

What looping process checks the test condition at the end of the loop?
The do..while() loop tests the condition at the end of the loop. Therefore the loop body executes at least once. The while() loop (without do) tests the condition before entering the loop and before each iteration of the loop. The for() loop conditional expression is optional but, when specified, is tested before entering the loop and before each iteration of the loop.
What is difference between while and dowhile?
the test condition will be checked first after wards the body of the loop will be excuted in while statement and the the do while statement represented the body of the loop will be executed first and then the test condition will checked next
What is for looping in c language?
The for loop is another entry-controlled loop that provides a more concise loop control structure.The general form of the for loop isfor( initialization ; test condition ; increment ){body}Generally this loop is used when the either the no. of loops or the looping condition or the end condition is known.Ex.to count n no. of integers.Hope this will help.
Is a for loop a post-test loop?
Yes. The second clause (the condition) is evaluated before each iteration through a loop. It is possible that a for loop will not execute if its precondition is not met. For example, "for( int x = 5; x < 5; x++ )" will not iterate even once.
What is the difference between entry and exit controlled loops - in Java?
while loop and for loop are entry controlled loops as they check looping condition at the entry point. do while loop is exit controlled loop as it checks looping condition at exit point. shreeradha@yahoo.com
What is the difference between do while and while loop in java?
A do-while loop guarantees the body of the loop will execute at least once. A while loop might not execute at all. // this code will execute, even though the condition test will always evaluate to false do { // stuff }while(false); // this code will never execute because the condition test will always evaluate to false while(false) { // stuff }
