A for loop is used to specify an iteration that allows code to be executed repeatedly. This is a famous loop because of its flexibility and convenience. The for loop works with lists, arrays, collections, or ranges; it can be a range of integers or a collection of objects. The for loop also requires a control variable with start and end values, iterates on a given range, and exits the loop automatically. In a nutshell, it takes care of most things that other loops are not able to take care of.
