for ( init-expr ; test-expr ; incr-expr )

C-style looping construct. init-expr assigns the initial value of a counter variable. test-expr is a relational expression that is evaluated each time before executing the statement . When test-expr is false, the loop is exited. incr-expr increments the counter variable after each pass. All the expressions are optional. A missing test-expr is considered to be true. A series of statements must be put within braces.
