Answer 1

The "while" can be applied to a program where the number of iterations is not known before hand.

Explanation:

Looping is the act of repeating something until a certain condition is satisfied. Loops are mainly used to iterate through arrays or repeat cօde specific amount of times. It's saves our time and execute cօde repeatedly.

When something is unknown, "while" is used more often. You don't know when it will be valid, the process will be repeated until it is valid.

With continued use you will notice that "for" is used more when you have a specific time for repeat it over and over again. A good example is if you want to count from zero to ten.
