Question
A pointer is basically a reference to an object or a function. In fact, it is a variable that holds memory address. This address is the
location of some other variable or object in memory. For example, if one variable contains the address of another variable, first
one is said to point to the second one. Pointers may have many uses, such as to make functions implement “call-by-reference"
methodology and to construct dynamic arrays or structures at run-time.
