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("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.
