In computer science a for loop is a programming language statement which allows code to be repeatedly executed. A for loop is classified as an iteration statement.For loops are also typically used when the number of iterations is known before entering the loop.

A for loop is used to repeat a statement until a condition is met. frequently are used for simple iteration in which a statement is repeated times, for loops can be used for just about any kind of loop.

The for loop provides a simple mechanism for repeating a code block a fixed number of times or for iterating through a set of values.

The for statement provides a compact way to iterate over a range of values. Programmers often refer to it as the "for loop" because of the way in which it repeatedly loops until a particular condition is satisfied.
