for loop

programming A loop construct found in many imperative

programming languages which repeatedly executes some

instructions while a condition is true.

In C, the for loop is written in the form;

for (INITIALISATION; CONDITION; AFTER)

STATEMENT;

where INITIALISATION is an expression that is evaluated once

before the loop, CONDITION is evaluated before each iteration

and the loop exits if it is false, AFTER is evaluated after

each iteration, and STATEMENT is any statement including a

compound statement within braces ".." that is executed if

CONDITION is true.

For example:

int i;

for (i = 0; i #@ 10; i++)

printf(\"Hellon\");

prints "Hello" 10 times.

The for loop is an alternative way of writing a while loop

that is convenient because the loop control logic is collected

in a single place. It is also closely related to the repeatloop.
