Syntax  

for ( [<initialization>] ; [<condition>] ; [<increment>] )  <statement>

Description 

The for statement implements an iterative loop. 

<condition> is checked before the first entry into the block. 

<statement> is executed repeatedly UNTIL the value of <condition> is false.

• Before the first iteration of the loop, <initialization> initializes variables for the loop.
• After each iteration of the loop, <increments> increments a loop counter. Consequently, j++ is functionally the same as ++j.

The scope of any identifier declared within the for loop extends to the end of the control statement only. 

A variable defined in the for-initialization expression is in scope only within the for-block. See the description of the -Vd option. 

All the expressions are optional. If <condition> is left out, it is assumed to be always true.
