AHPA #10: The Secure Array * * Using pointers, access Peter's array without him knowing it * and place three values that you got from the user (101, 63, * 21) at locations 3, 6, and 9. Recalculate the sum value and * update it. ( the output should be same as the picture)
This lab will exercise your understanding of some of the concepts covered in Chapter 12:dynamic data, arrays, pointer addresses 1. Create a structure called students. The structure should contain:firstname, lastname, gpa. 2. Create a pointer to the student structure and dynamically create an array of thestudent structure, enough for 4 students.Hint: Store the address of the beginning of the array 3. Create a file that contains four rows of data with last name, first name and gpa valueor use the inFile.txt file attached. 4. Using pointer notation only (not array notation []), read the data from the file andstore the data into the structure.After all the data is read and stored, using pointer notation only, output to the console (cout)each student's first name, last name and gpa. Use information messages and ensure the datais displayed properly. 5. Before exiting, delete the dynamically allocated structure array.Complete as much as you can before you leave ensuring what you've completed…

It shouldcreate a new array that is the same size as the argument. It should set the values inthe new array by adding 10 to each element in the original array.

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.
Task1:In the driver file (main.cpp), perform the following sub-tasks.1.Create two objects of this class, one with no constructor argument and one with the argument 5. 2.Take five input values from the user and store them in the array inside the second object using the set method. 3.For the second object, print all the values you just stored.Note that, you cannotassign anythingin the first object since the array inside it has size 0. Neither can you change the size ofthisarray to some other size. Task2:Modify the header and the source files.Add a member function void allocate(int s)which allows you to change the size of the array.Make sure that memory is not leaked. Task3:Modify the header file and the source files again, so that it works for two dimensional arraywhere all the rows are the same size. The user will specify the number of rows and columnsas well as the content of the array, which you will take as input from user in the main function. Solve these task using C++
Write the code that dynamically allocates memory for an array of 10 integers and assigns its address to the pointer ptr. After that use that pointer to access the array and store on it the powers of two then display the content of the array on the screen. The output should be: 2 4 6 8 16 32 128 256 512 1024. Note: You can use the pow() function. This function takes two arguements and returns the result of the first argument raised to the power of the second arguement.
C++ The People class holds an unsorted list of humans. Initially, this list is empty. Upon inserting a Human object, it is added to the array at the next available position and the position value in incremented. If the position value is equal to the size value, do not insert the Human. Instead, throw an exception that your driver can catch to print an error that the People object is full. Create a People class with the following features: Each People object has a statically allocated array of Human objects. Size attribute representing the maximum size of the array. Position attribute representing the next free position in the array. Default constructor with no arguments. Search method that takes a string argument and returns a Human object. This method returns the first Human object with a name matching the string argument. In other words, pass the name of a Human as a string, search the list of humans for one with that name. If found, return this human. Else throw an…
(1) Create a cpp file Array Operations under Source files folder. Write a program in C++ to declare an array called mark. This array will store marks of an assessment like practical, assignment or test for 16 students. Therefore, the size of the array should be 16. a. Number of available marks are 10 for ten students, however there are 16 students, therefore, the remaining marks will be read into the program while the program is running. For now, initialize the array with given marks. 7.3 8.6 10.65 16.4 13.5 6.35 17.3 4.4, 8.5, 12.7 b. With reference to unavailability of remaining 6 marks in part a, write codes to read these remaining six marks and add them at the end as you read. c. Write codes to count the numbers above the average. d. Write codes to determine the highest mark a student scored. e. Display all the important data and results with descriptive relevant labels. [At the end of this activity, comment out your program, so that you next program of activity 2 below will…
