Grasp the concept of pointers and references from "summary" of C/C++ Programmer's Reference by Herbert Schildt
Pointers and references are two important concepts in C/C++ programming that allow you to work with memory addresses. Pointers are variables that store memory addresses, while references are aliases for existing variables. Understanding pointers is essential in C/C++ programming because they allow you to directly access and manipulate memory locations. By using pointers, you can pass variables by reference, dynamically allocate memory, and create complex data structures such as linked lists and trees. To declare a pointer, you use an asterisk (*) before the variable name, like this: int *ptr; This declares a pointer named ptr that can store the memory address of an integer variable. You can then assign the address of a variable to the pointer using the address-of operator (&), like this: ptr = # This assigns...
