The general form of the for statement can be expressed as follows: When using this version of the for statement, keep in mind that: 1  The initialization expression initializes the loop; it's executed once, as the loop begins. 2  When the termination expression evaluates to false, the loop terminates.
Statement(s) True False Figure 5.1: Execution ow in an if statement 50 > if (x > 100) y = 2; > y 50 Notice that y is initially 40, as expected. The rst if statement reassigns y to be 50, but the second if statement does not reassign y to 2. In the rst case the Boolean expression x > 10 is true, but in the second case x > 100 is false. In both cases the reassignment of y is conditional on the value of x . As shown above, a single if statement spans two lines.
