pre-test
No reason. It is a post-test loop.
It is 'pre-test' and 'post-test'.
The difference is that pre means before and post means after in Latin so it's tested before or after. :)
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.
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.
The test condition in a loop is what's used to determine when the loop should end.
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.
Executing a segment of a program repeatedly by introducing a counter and later testing it using the if statement.A sequence of statements are executed until some conditions for termination of the loop are satisfied.A Program loop consists of two segments:1.Body of the loop2. Control StatementDepending on the position of the control statement in the loop, a control strcture may be classifies either as the 2:Entry Controlled LoopExit Controlled Loop1.Entry Control Loop-(Pre Test Loop)The control conditions are tested before the start of the loop execution.If the conditions are not satisfied , then the body of the loop will not be executed.]eg:While Loop2.Exit Control Loop-(Post Test loop)The Test is performed at the end of the body of the loop and there fore the body is executed unconditionally for the first time.eg:Do-Whilewhile loopfor loopdo-while loop
A for loop.
Murry for long underground cables test but varley usually for short distance.
for 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.
