- 17. www.edureka.co Why FOR Loop? When we are iterating over a sequence. You know the number of times the statements will get executed.
- 18. www.edureka.co Why WHILE Loop? When we are executing a set of statements , if the condition holds true. The execution stops as soon as the condition is false.
