How do you use smart pointers when trying to call a library function that was written before smart pointers were developed? Instead of passing smart pointers to functions, normally, you'll retrieve the smart-pointer's raw pointer using get(), and call the function with that. Complete the code below to double Frank's salary and to print his information. You may use a shared_ptr or a unique_ptr.

- Pointers are by default passed by value in a function. Group of answer choices True False ================= Given the below code segment, which of the following would allow you to deallocate all memory allocated to the pointer numbers? int* numbers = new int[5]; Group of answer choices delete[] numbers; delete numbers; delete[5] numbers; None of these ========== Consider the following code: int arr[][4] = { {1, 2, 3, 4}, {7, 8, 9, 10} }; cout << arr[1] << endl; What will be the output? Group of answer choices 1 7 Address of 1 Address of 7 Compilation error: Second [] bracket missing with arrFor 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);Is that right?For functions that are flexibly bound, you need pointers or references.
- The following describes the difference between void and NULL pointers: Make proper use of examples to bolster your argument.This lab will exercise your understanding of some of the concepts covered in Chapter 14: pointers and linked lists 1. Declare an integer pointer variable intPointer. Initialize it to point to an int variable named someInt. Assign the value 451 to someInt and output (cout) the variable someInt and output (cout) the value pointed to by intPointer. Write an assignment statement that indirectly stores 900 into the value pointed to by intPointer. Output (cout) the value pointed to by intPointer and output (cout) the variable someInt, 2. Declare a pointer variable charArrPointer and initialize it to point to the first element of a three-element char array named initials. Write assignment statements to store 'A', 'E', and 'W' into the first three elements of the array POINTED to by charArrPointer. Do NOT store any values directly into the array named initials. 3. Output (cout) the data in array charArrPointer and the data in array initials. 4. Copy the following code into your program above…Write in C++ Sam is making a list of his favorite Pokemon. However, he changes his mind a lot. Help Sam write a function insertAfter() that takes five parameters and inserts the name of a Pokemon right after a specific index. Function specifications Name: insertAfter() Parameters (Your function should accept these parameters IN THIS ORDER): input_strings string: The array containing strings num_elements int: The number of elements that are currently stored in the array arr_size int: The number of elements that can be stored in the array index int: The location to insert a new string. Note that the new string should be inserted after this location. string_to_insert string: The new string to be inserted into the array Return Value: bool: true: If the string is successfully inserted into the array false: If the array is full If the index value exceeds the size of the array
- 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; }Inspect the code and in your own interpretation, describe the reason call to function ChangeIt_1(n) will not change x in main()? Inspect the code and in your own interpretation, describe the reason parameter n in ChangeIt_2(int *n) is a pointer, and statement in the function is *n = 6 ? Write a function called void swap with two parameters, which will receive the address of x and y as pointer. The function should swap the value of x and y only if x is larger than y. Print the value of x and y after the function call. Write a function called double getAverage(int *array, int SIZE), where it accept the array as pointer, and return the average of the array. Print the returned value from this function. Always use *array rather than subscript to access the array value.Write a complete C++ code that inputs a character array (string) from a user. After taking input it callsa function Reverse() that reverses the string word by word as shown below:Original Character Array:Raining in summers makes your life prettyAfter calling Function Reverse():pretty life your makes summers in RainingNote: You have to use pointers in the function. You can use any builtin Cstring function of your choice for thistask.
- Please write C++ functions, class and methods to answer the following question. Write a function named “removeThisWord” that accepts the vector of pointers toWord objects and a search word. It will go through that list and remove all Wordobjects with the same search word from the vector object. It will return how manyWord objects have been removed. I need the carrect answer as soon as possible please1. 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.Programming language C Write your own implementation for the functions above, where the names of the functions will be:my_strcmpmy_strncmpmy_strchrrespectively. In addition, write a program (a function called main (which allows receiving data, runningThe functions you wrote and printing their results.2 Note 1: In the implementation of the standard library for the strchr function, the return value of the function isfrom a pointer type. In the realization that you must write (strchr_my, the function must return an int value, which indicates theThe index of the character from the beginning of the array. If the character is not found, a negative number (minus one) must be returned.Note 2: The following "input word" can be received (where "input word" is defined as a collection of characters betweenTwo "white" characters - space, t, \or n (\by using the scanf command as follows:scanf(“%s”, character_vector_name);;which will cause the next "input word" to be read, into the array whose name…
