For C++, How would I call or use a function that is passed by pointer or a reference? How would I use these in this example below? I understand how passing by value works, but when it comes to passing by references and pointers, that is when I get confused. #include <iostream> using namespace std; // passing by reference in this function void pass_ref(int &ref); // passing by pointer in this function void pass_ptr(int* ptr);
The Challenge: You must build a pointer to a function that accepts an integer input and returns an array of pointers to functions that accept a single string parameter and return an integer.Whew! You have to read the specification at least three times before you realise you don't comprehend it.How do you handle something so complicated.
The input string is provided as a parameter to the compress_string function.

The Problem: You need to create a pointer to a function which takes a integer argument and returns an array of pointers to functions which take one argument, a string, and return an integer. Whew! That's a specification you have to read at least three times to figure out that you can't understand it.How do you deal with such complexity.

What's the distinction between void and NULL pointers? Give appropriate examples to back up your answer. Give the distinctions in TABULAR form.
Is that right?For functions that are flexibly bound, you need pointers or references.
in C Given the code below, what would be the proper way to pass the pointers ptr_1, and ptr_2, to the function mix () defined below? #include <stdio.h> void mix( float *, float * ); int main (void) { float *ptr_1, *ptr_2; mix( ?, ? ) <--- What is the correct way to call the function mix (), and pass the pointer variables ptr_1, ptr_2? return 0; }
1. Inspect the code and in your own interpretation, describe the reason call to functionChangeIt_1(n) will not change x in main()? 2. Inspect the code and in your own interpretation, describe the reason parameter n inChangeIt_2(int *n) is a pointer, and statement in the function is *n = 6 ? 3. Write a function called void swap with two parameters, which will receive the addressof x and y as pointer. The function should swap the value of x and y only if x is larger thany. Print the value of x and y after the function call. 4. Write a function called double getAverage(int *array, int SIZE), whereit accept the array as pointer, and return the average of the array. Print the returnedvalue from this function. Always use *array rather than subscript to access the arrayvalue.
Write a C++ function that uses pointer notation only to swap the contents of two integer arrays whose size is equal to SIZE?

Is that correct?Pointers or references are required for dynamically bound virtual functions.
