Loops

There may be a situation when we need to execute a block of code several number of times, and is often referred to as a loop.
Every Language has very flexible three looping mechanisms. You can use one of the following three loops:

For Loop
While Loop
Do .. While Loop

The for Loop:

A for loop is a repetition control structure that allows you to efficiently write a loop that needs to execute a specific number of times.
A for loop is useful when you know how many times a task is to be repeated.

Syntax:

for(initialization; Boolean_expression; update)
{
   //Statements
}

Here is the flow of control in a for loop:

initialization	statement executed once when beginning loop
Boolean	if the test evaluates to true, the statements execute
update	executes at the end of each iteration
statements	collection of statements executed each time through the loop
