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.

In C++, <initialization> can be an expression or a declaration. 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.
