In this chapter we will continue to use the console application format of Visual C++ to move further into PC programming and especially to prepare for the discussion of C++ classes and objects presented in Chap
Pointers, Arrays, and Structures(Chapter 5 of The C++ Programming Language) No object is allocated with the address 0 . Consequently, 0 acts as a pointer literal, indicating that a pointer doesn’t refer to an object. The declarator operator that makes a pointer constant is *const. There is...

pointers allow us to manipulate data in the memory of the computer. Pointers make it easier to handle complex data structures and efficient management of the memory. When parameters are passed to functions, pointers can directly modify the original data rather than just working with a copy. More...
The correct way to compare strings is to use the standard library function strcmp() which will compare the strings character by character. Because strings in C are just arrays of characters (or simply a string of characters stored in sequential memory locations) terminated by a null character, ...
One Dimensional Arrays in CArray name in C language behaves like a constant pointer and represents the base address of the array. It points to the first element of the array which is located at 0th index. As array name serves like a constant pointer, it cannot be changed during the ...
C# supports pointers in a limited extent. A C# pointer is nothing but a variable that holds the memory address of another type. But in C# pointer can only be declared to hold the memory address of value types and arrays. Unlike reference types, pointer types are not tracked by the ...
Arrays of Pointers Sometimes a great deal of space can be saved, or certain memory-intensive problems can be solved, by declaring an array of pointers. In the example code below, an array of 10 pointers to structures is declared, instead of declaring an array of structures. If an array of...
Pointers are used in C to achieve pass-by-reference semantics, allowing functions to modify variables passed as arguments, to navigate through arrays efficiently, and to manage dynamic data structures. Basic Pointer Operations Basic operations with pointers include dereferencing, arithmetic operations, ...
