The For Loop Explained with DSA Examples

Can a for loop run backward?

The answer

Yes. You can initialize the counter at a high value, use a greater-than condition, and decrement the counter (e.g., i--).

More FAQs in The For Loop Explained with DSA Examples

Use a for loop when you know exactly how many times you need to iterate, such as when traversing an array of known length.

It is the increment operator. It means 'increase the value of i by 1' after each iteration of the loop.

It occurs when your loop condition tries to access an array element that doesn't exist, usually by looping one time too many (e.g., using i <= array.length).
