For Loop ?

How for loop works?

Iitialization of the loop variable

Test of the loop repetition condition.

Change(update) of the loop control variable.

The initialization section can be used to declare a variable.

Like a while loop, the condition of a for loop is tested prior to executing the loop body.

Therefore, the body of a for loop will execute zero or more times.

The increment section can perform any calculation.

A for loop is well suited for executing statements a sepecific number of times that can be calculated or determined in advance.

Syntax :

   for ( initialization; condition; increment/decrement; ) 
  {
   statement(s);
   }
