Detailed explanation-1: -A for loop repeats a block of code, but it’s more configurable than a while loop. A for loop is also the preferred tool for counting tasks. while loops are better for repeating something “while” a condition is true. In contrast, for loops are better for repeating a block a certain number of times.
Detailed explanation-2: -A counting loop, or counter-controlled loop, is a loop in which you know beforehand how many times it will be repeated. Among the preceding examples, the first two are counting loops. In this case, the counter is the variable k, which counts from 0 through 99-that is, it counts 100 times.
Detailed explanation-3: -A “For” Loop is used to repeat a specific block of code a known number of times. For example, if we want to check the grade of every student in the class, we loop from 1 to that number. When the number of times is not known before hand, we use a “While” loop.
Detailed explanation-4: -The loop counter is used to decide when the loop should terminate and for the program flow to continue to the next instruction after the loop.
