What is the storage of pointer in C?
A pointer is a data value that references a unit of storage.
Also, I would like to point out that we can achieve the same implementation by doing the following: int *A, *B; The latter will have the same exact effect as: pointerToInteger A, B; declaration.What is pointer in storage?
Pointers take up the space needed to hold an address, which is 4 bytes on a 32-bit machine and 8 bytes on a 64-bit machine. In C++, every value is stored somewhere in memory and can therefore be identified with that address. Such addresses are called pointers.What is the storage size of pointer?
Unlike normal variable which stores a value (such as an int , a double , a char ), a pointer stores a memory address.
