Chapter 9, Problem 28RQE
Look at the following function definition:
void getNumber(int &n)
{
cout ≪ "Enter a number: ";
cin ≫ n;
}
In this function, the parameter n is a reference variable. Rewrite the function so n is a pointer.

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."

int s=1*2;
}
cout << s;

C++
C Program Functions using Pointers
Create a function modify that accepts an integer and divides the integer by 2 if it is even. If the integer is odd, add one and divide it by 2. The function does not return anything.
In the main function, write a program that asks for an integer input and call the modify function by passing in the reference of that variable as a parameter.
An initial code is provided for you. Just fill in the blanks.
Input
1. One line containing an integer input
Output
Enter a number: 5
Before: 5
After: 3
pointers 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.
