Introducing the for()… statement

The for()… statement has the following syntax:

for( counter_initialization ; continuation_expression ; counter_increment ) statement_body

The for()… statement consists of a three-part control expression and a statement body. The control expression is made up of a counter_initialization expression, continuation_expression, and a counter_increment expression, where a semicolon separates each part of an expression. Each one has a well-defined purpose. Their positions cannot be interchanged.

Upon executing the for()… statement, the counter_initialization expression is evaluated. This is performed only once. Then, continuation_expression is evaluated. If its result is true, the statement_body is executed. At the end of statement_body, the counter_increment expression is evaluated. Then, the process repeats, with the evaluation of continuation_expression. When continuation_expression evaluates to false, the loop ends;...
