Chapter 10.12, Problem 10.20CP
Program Plan Intro
Pointer:
Pointer is a special type of variable to store the address of the memory location, which can be accessed later.
- If an asterisk “*” operator is present before the variable, then that variable is referred as pointer variable.
- It is also called as dereferencing or indirection operator.
- Pointer is just a type of variable that stores the addresses of other variables.
- Using pointers, the address of a variable can be accessed and the data stored in that variable can be retrieved.
Syntax of pointer variable declaration:
<variable-type> *<variable-name>;
Usage of pointers to structures:
The usage of pointers to structure is same as declaring a pointer variable.
