Chapter 10, Problem 20RQE
Explanation of Solution
Returning a pointer from the function:
Pointers can be returned from the function only if the reference pointer variable exists in the function.
Circumstance for successful return of a pointer:
The circumstances for returning pointer successful are listed below:
- When a pointer is passed as an argument in a function that is called.
- When a pointer variable is defined locally within the function there may be possibility for the contents of the variables being destructed after execution of the function...
