The while loop differs from the do-while loop in one important way — with a while loop, the condition to be evaluated is tested at the beginning of each loop iteration, so if the conditional expression evaluates to false, the loop will never be executed.

For example, Control flow. v. t. e. In most computer programming languages, a do while loop is a control flow statement that executes a block of code and then either repeats the block or exits the loop depending on a given boolean condition. The do while construct consists of a process symbol and a condition. First the code within the block is executed. do. {. // body of while loop. } while (true); The infinite loop is useful when we need a loop to run as long as our program runs. For example, if your program is an animation, you will need to constantly run it until it is stopped. In such cases, an infinite loop is necessary to keep running the animation repeatedly.A while loop, naively, has to be implemented as two jumps. while (X) { Y Z } This must be implemented at a low-level as something like this. loop: X jump_if_false end_loop Y Z jump loop end_loop: A do ... while loop, on the other hand, is always exactly one conditional jump, even with no optimizations applied.
