Question

difference between for loop and while loop

Answer 1

for loop will be used when we know how many number of iterations we needed to do and
while is used when we don't know how many iterations do we require to do
and also
in some cases we can use both for / while loop anyone would be great.

Answer 2

Feature	for Loop	while Loop
Best used when	Number of iterations is known	Number of iterations is not known in advance
Structure	Initialization, condition, and update are written together	Initialization and update are usually written separately
Readability	More compact for counting loops	More flexible for condition-based loops
Common use	Traversing arrays, repeating a fixed number of times	Reading input until a condition changes, waiting for an event
