Detailed explanation-1: -The purpose of a loop is to repeat a set of statements. Whenever you create a loop, you eventually need to make the loop stop. The most primitive way to do this is to specify the number of loop repetitions.
Detailed explanation-2: -A while loop repeats a block of code an unknown number of times until a condition is no longer met. for loops, on the other hand, repeat a block of code a fixed number of times. So, a while loop is useful when you don’t know how many times you want a block of code to execute beforehand.
Detailed explanation-3: -The for loop is used to repeat a section of code known number of times. Sometimes it is the computer that knows how many times, not you, but it is still known.
Detailed explanation-4: -Fixed loop-This is where the loop repeats a sequence of code a set number of times. Conditional loop-This kind of loop keeps repeating code until a condition is met.
Detailed explanation-5: -A repeat loop is used any time you want to execute one or more statements repeatedly some number of times. The statements to be repeated are preceded by one of the repeat statements described below, and must always be followed by an end repeat statement to mark the end of the loop. Repeat loops may be nested.
