==Synopsis==

for(init; expr2; expr3) statement;

==Description==

Execute <init> once. Then, while <expr2> returns a non-zero
value, execute <statement>. Every time <statement> has been
executed, or a 'continue' statement has been executed, execute
<expr3> before next loop.

<init> is usually a series of one or more expressions (remember
that assignments are expressions, too), separated by commas.
Additionally it is also allowed to define new local variables
here and assign them an initial value. The scope of such variables
is the whole for statement.

Examples for legal <init> expressions are:

for (i = 0; ...
for (i = 0, j = 0; ...
for (i = 0, int j = i; ...
for (int j = 4; ...

Illegal <init> expressions are:

for (int i; ... : no value assigned
for (int i += 4; ... : only plain assignments allowed

A 'break' in the 'statement' will terminate the loop. A
'continue' will continue the execution from the beginning of
the loop.
