... In C, you could allocate memory with the library function malloc(). You still can do so in C++, but C++ also has a better way, the new operator. Let's try out this new technique by creating ... wherever you use array notation, C++ makes the following conversion: arrayname[i] becomes *(arrayname + i) And if you use a pointer instead of an array name, C++ makes the same conversion...

... C++ programming. As your experiences enhance your understanding and appreciation of these features, begin adding other C++ features. As Bjarne Stroustrup, the creator of C++, suggested at a C++ ... (op is *). The op has to be a valid C++ operator; you can't just make up a new symbol. For example, you can't have an operator@() function because C++ has no @ operator. But t...

... bp->ViewAcct() goes by the object type (BrassPlus) and invokes BrassPlus::ViewAcct(). In this example, you can see the object type is BrassPlus, but, in general, (as in Listing 13.10) the ... points to a BrassPlus object. If the destructors are virtual, the destructor corresponding to the object type is called. So if a pointer points to a BrassPlus object, the BrassPlus destructor ... s...
