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.
If I have a parent class A which has data in it that needs to be initialized (and is initialized in A's constructor), when I derive class B from A, will A's constructor be run along with B's, or do I need to copy the initialization code from A's constructor to B's constructor so that the data in A is initialized when a B member is instantiated?
