Example text

It makes sure that the file specified by the user does not already exist (or that it is all right to overwrite it if it does exist) before opening it for output. • It makes sure that the file exists before attempting to read from it. (Hint: After the call to open, you can test the ifstream variable as if it were a bool. 11. " const can be applied usefully in a large number of programming situations, as we will soon see. Because it cannot be assigned to, a const object must be properly initialized.

The new operator allocates storage from the memory heap (also called the heap, free pool, or free storage) and returns a pointer to the newly allocated object. 9). In general, the code that calls new should document, or be physically located near, the code that frees the memory. The goal is to keep memory management code as simple and reliable as possible. The delete operator releases dynamically allocated memory and returns it to the memory heap. delete should be applied only to pointers returned by the new, or to null pointers.

Pointers can seem complicated at first. We discuss pointer use and misuse in more detail in Chapter 22. 1. The Unary Operators & and * A variable is an object with a name recognized by the compiler. A variable's name can be used as if it is the object itself. For example, if we say: int x = 5; we can use x to stand for the integer object whose value is 5, and we can manipulate the integer object directly through the name x. For example: ++x ; // symbol x now refers to an integer with value 6 An object (in the most general sense) is a chunk of memory that can hold data.
