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...

- Using C++ Programming language: Assume you want a function which expects as parameters an array of doubles and the size of the array. Write the function header that accepts these parameters but is defined in such a way that the array cannot be modified in the function. You can use your own variable names for the parameters.arrow_forwardWhen passing many arguments to a function, does it matter in what sequence those arguments are passed?arrow_forwardTRUE or FALSE - In C++, a function can't return a pointer. Select one: a.FALSE b.TRUEarrow_forward
- How do you declare a pointer variable? Does a local pointer variable have a default value?arrow_forwardHow may the address of a variable be added to a pointer variable? Why is the code below problematic?arrow_forwardpointers as Arguments:In the C programming language there is no pass-by-reference syntax to passa variable by reference to a function. Instead a variable is passed by pointer(just to be confusing, sometimes passing by pointer is referred to as pass byreference). This Practice Program asks you to do the same thing as C.Here is the header for a function that takes as input a pointer to an integer:1. void addOne (int ∗ptrNum )Complete the function so it adds one to the integer referenced by ptrNum.Write a main function where an integer variable is defined, give it an initialvalue, call addOne, and output the variable. It should be incremented by 1.arrow_forward
- 3- It is not possible to change the value of the pointer. (True or False). 4- If the following lines of code have errors, correct them; otherwise, write "no errors." for (int i=2; i<5; i++) { int s=1*2; } cout << s; 5- A function cannot be called from inside another function. (True or False). 6- How to make a function return multiple values? 7- Every class member is by default. (public, private, not public nor private) 8- Create an instance of the following class and call its methods. class Exam{ int grade; public: void seta (int b) (grade=b; } int geta () {return grade; } 9- When the word const is put before the variable definition, what does that mean? 10- How to concatenate two strings in C++ language?
