In the STATIC example in before chapter, “Objects and Classes,” we introduced static data members. As you may recall, a static data member is not duplicated for each object; rather a single data item is shared by all objects of a class. The STATIC example showed a class that kept track of how many objects

In this section we’ll introduce a new kind of unified modeling language UML diagram: the state diagram (also called the statechart diagram). The UML class diagrams we examined in earlier chapters show relationships between classes. Class diagrams reflect the organization of the program’s code. They are static diagrams, in that these relationships (such as association

Our next example demonstrates an array of pointers to objects, and shows how to sort these pointers based on data in the object. This involves the idea of pointer to pointer, and may help demonstrate why people lose sleep over pointers. The idea in the next program is to create an array of pointers to

Memory Management : We’ve seen many examples where arrays are used to set aside memory. The statement int arr1[100]; reserves memory for 100 integers. Arrays are a useful approach to data storage, but they have a serious drawback: We must know at the time we write the program how big the array will be. We
