Some C programming tasks are performed more easily with pointers, and other tasks, such as dynamic memory allocation, cannot be performed without using pointers. The text focuses on pointers and memory in compiled languages like C and C++. Note that, when printing &c (address of c), we use %u rather than %d since address is usually expressed as an unsigned integer (always positive). Note: You may obtain different value of address while using this code. However for manipulating certain data structures, the use of pointers can simplify the code, and knowledge of manipulating pointers is handy to have in Notes on Pointers. 4 Arrays and pointers, dynamic allocation 37In C arrays and pointers can always be used interchangeably. Pointers store address of variables or a memory location. They are based on notes prepared (beginning in Spring, 1995) to supplement the book The C Programming Language, by Brian Kernighan and Dennis Ritchie, or K&R as the book and its authors are affectionately known. Like any other variable in C, a pointer-valued variable will initially contain garbage---in . at run time. A callback in procedural languages, such as C, may be performed by using function pointers. C Notes Relation Between Pointers and Arrays Space for static arrays in C is allocated on the stack when the function that defines them is called and is automatically deleted when the function ends, just like any other local variable. It provides power and flexibility to the language.
