Run the following program and answer the questions. #include int main() { int a[5] = {4,16,19,12,16}; int *arr_pointer = &a[0]; *arr_pointer = a[*arr_pointer]; arr_pointer++; printf("%d\n", *arr_pointer); return 0; } 1. For each line of the main function (lines 5 through 8 in particular), consider how the variable a changes as the program progresses. Explain what the value of a is at each major line and why it has such value. (Hint: the gdb step command is very helpful for this problem).

3. Pointers – Arrays: initializing content • Using the pointer ptrArray, you now want to write values in those integers. Use a loop to go through each element in that array, and initialize them all to 42. This is done in the main. 4. Pointers – Arrays: printing • Write a function that will print the elements in the array-pointer. The function should accept a pointer to an integer, and the size of this array. The function should not return anything. Here is your function prototype: void printArray(int* ptr, int nb); • Your function needs to use a loop to go through all the elements in the array, and simply prints them on a new line. • In the main function, call this function with your pointer ptrArray and the size given by the user.

Given main() and pointer_funcs.h, write the four functions in the TODO outlined below.

//main.cpp file #include <iostream> #include "helper.h" #include "sorting.h" using namespace std; int main() { unsigned int size; cout << "Enter the size of the array: "; cin >> size; int* Array = new int[size]; unsigned int choice = 0; do { fillRandom(Array, size); cout << "Choose your sorting algorithm:" << endl; cout << "1. Bubble Sort" << endl; cout << "2. Selection Sort" << endl; cout << "3. Insertion Sort" << endl; cout << "4. Merge Sort" << endl; cout << "5. Quick Sort" << endl; cout << "6. Shell Sort" << endl; //Optional cout << "Enter 0 to exit" << endl; cout << "Your choice: "; cin >> choice; cout << "Unsorted Array: "; print(Array, size); /***************************** TODO: Implement what you will do with the choice*****************************/ cout << "Sorted Array: "; print(Array, size); } while(choice!=0); delete [] Array; return 0; }...

C+++ CODE HELP WITH POINTER BASICS CODE TO DO THE FOLLOWING: In function DisplayRank(), if rankPointer is null, print "rankPointer is null.". Otherwise, print the value in the variable pointed to by rankPointer. End with a newline. Ex: If the input is Y D, then the output is: D #include <iostream>using namespace std; void DisplayRank(char* rankPointer) { /* Your code goes here */ } int main() { char rank; char* rankPointer; char action; rank = '0'; cin >> action; cin >> rank; if (action == 'Y') { rankPointer = &rank; } else { rankPointer = nullptr; } DisplayRank(rankPointer); return 0;}

IN C PROGRAMMING LANGUAGE: Please write a pointer version of squeeze() named psqueeze(char *s, char c) which removes c from the string s.

Write a JAVA program that will maintain a phone directory using Classes, and Objects. The programshould be able to perform the following operations:1.Add persons details (first name, last name, phone number, city, address, sex and email) to the phonedirectory, where phone numbers in the directory have to be unique. (Note: each person record will store inClasses and Objects)2.Update telephone number by providing person first name.3.Display all details of persons from a phone directory.4.Search telephone number based on person first name. (Note: use sequential search to find all telephonesfor the given first name)Project OutputsThe output has to display a menu of choices. Then the user can select which operation want to perform.Also, you can use the method System.exit(0); to exit the program. The menu of choices will be:1) Add person details into the telephone book.2) Update a telephone number by providing person first name.3) Display the entire telephone book.4) Search a telephone...

C++, Please add a function where it can display the median, the maximum number, the minimum number, in an array entered by the user. Code: #include<iostream> using namespace std; class Search_Dynamic_Array { public: Search_Dynamic_Array(); int getArrSize(); void getArray(); void setArrsize(int); void setArray(int*); int getSum(int*); private: int arr_size; int arr[]; }; Search_Dynamic_Array::Search_Dynamic_Array() { //ctor } int Search_Dynamic_Array::getArrSize() { return arr_size; } void Search_Dynamic_Array::getArray() { cout << "The elements of the array are: "; for(int i=0; i<arr_size; i++){ cout << arr[i] << " "; } } void Search_Dynamic_Array::setArrsize(int s) { arr_size=s; } void Search_Dynamic_Array::setArray(int a[]) { for(int i=0; i<arr_size; i++){ arr[i]=a[i]; } } int Search_Dynamic_Array::getSum(int a[]) { int sum; for(int i=0; i<arr_size; i++){ sum +=arr[i]; } return sum; } int main() { int s=1, a[s]; cout << "Enter the size of the...

1- Write a user-defined function that accepts an array of integers. The function should generate the percentage each value in the array is of the total of all array values. Store the % value in another array. That array should also be declared as a formal parameter of the function. 2- In the main function, create a prompt that asks the user for inputs to the array. Ask the user to enter up to 20 values, and type -1 when done. (-1 is the sentinel value). It marks the end of the array. A user can put in any number of variables up to 20 (20 is the size of the array, it could be partially filled). 3- Display a table like the following example, showing each data value and what percentage each value is of the total of all array values. Do this by invoking the function in part 1.

use c++ Programming language Write a program that creates a two dimensional array initialized with test data. Use any data type you wish . The program should have following functions: .getAverage: This function should accept a two dimensional array as its argument and return the average of each row (each student have their average) and each column (class test average) all the values in the array. .getRowTotal: This function should accept a two dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a row in the array. The function should return the total of the values in the specified row. .getColumnTotal: This function should accept a two dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a column in the array. The function should return the total of the values in the specified column. .getHighestInRow: This function should accept a two...
