Sure. Here is an example:
for (i=0; i<3; ++i) printf ("I am for loop, i=%d\n");
i=1;
while (i>0) { printf ("I am while loop, i=%d\n"); i <<= 1; }
A Loop is a programming language construct that instructs the processor to repeat a sequence of operations a number of times until a specific condition is reached. There are different types of loops. They are: * for loop * while loop * do while loop
We need a for loop because the while and do-while loops do not make use of a control variable. Although you can implement a counter inside a while or do-while loop, the use of a control variable is not as self-evident as it is in a for loop. Aside from the use of a control variable, a for loop is largely the same as a while loop. However, it is quite different to a do-while loop, which always executes at least one iteration of the loop before evaluating the conditional expression. In a for and while loop, the conditional expression is always evaluated before entering the loop, which may result in the loop not executing at all.
If you want to execute a statement which is in while loop at least one time you can use do- while loop. this is why because initially first statements will be executed then condition will be checked. but in case of while first condition will be check then statements will be executed
A nested loop is a (inner) loop that appears in the loop body of another (outer) loop. The inner or outer loop can be any type: while, do while, or for. For example, the inner loop can be a while loop while an outer loop can be a for loop.
They both loop
A Do-While loop looks like this: do { loop body } while (condition); and a While loop looks like this: while (condition) { loop body } The main difference is that the loop body is always run once in the Do-While loop, then the condition is checked to see if the loop should keep running. In a While loop, the condition is checked first, and it will not run the loop body at all if the condition is false.
Is loop
You mean PL/SQL? Well, they are different things, read the manual for details.
There are 3 type of loop 1 is for loop 2 is loop while 3 is loop untile
In any programming language, a "while" loop and a "do until" loop are the same except for 1 difference. In order to enter a while loop, the condition must always be true. But in a do until loop, if the condition was false, the block of code inside the loop will always be ran at least once. Example: while (false) { // code here } in this example, the code inside the while loop will never run, but in the following example: do { //code here } until(false) although the condition is false, the code will be run 1 single time and the exists the loop.
Yes. The same goes for for-loop and do-while-loop.
A for loop is classified as an iteration statement. A simple example might be... For x = 1 To 10 'loop body Next x The same loop expressed as a while loop (classified as a control flow statement) could be... x = 0 Do While x < 11 'loop body x = x + 1 Loop .
