The DO keyword.
The do keyword performs a simular function to
while. Basicaly, it repeats a block of statements.
Here is an example of the syntax:
printf(" i is %d\n", i);
The program result will look like this:
i is 5
i is 4
i is 3
i is 2
i is 1
The main difference between do and while is
the time that expression is evaluated.
- do performs the first test AFTER the first iteration.
- while performs the first test BEFORE the first iteration.
