The task of locating variables is automatically performed by the operating system during runtime. In some cases we need to know the address where the variable is being stored during runtime. Variable which stores a reference to another variable is called a pointer. We can directly access the value stored in the variable using a pointer which points to it. Syntax: 1. Pointer Declaration: Syntax: Pointer_type *Pointer_name; Example: int *Ptr1; double *Ptr2; 2. Pointer initializati
