for loop

for loop
for

   <programming> A {loop} construct found in many {procedural
   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("Hello\n");
    }

   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 {repeat
   loop}.
