Task - Using pointers to process arrays (C Languaage) In a TV show, each minute can be either interesting or boring. Assume that if 7 consecutive minutes are boring, then an average viewer will stop watching the show. Write a C program that calculates how many minutes that an average viewer will watch a TV show, given the interesting minutes. Assume the TV shows are 45 minutes long. Requirements Name your program project4_minutes.c. Follow the format of the examples below. The program will read in the number of interesting minutes, then read in the interesting minutes. The program should include the following function. Do not modify the function prototype. int find_minute(int *minutes, int n); minutes represents the input array for interesting minutes, n is the length of the array (the number of interesting minutes). The function returns the how many minutes an average viewer will watch the show. This function should use pointer arithmetic– not subscripting – to visit array…

In C++ Declare a constant “ SIZE = 5 ” Declare an array of ints , of size SIZE . Initialize that array to have the values 10, 12, 15, 19, 6 . – Write a loop that calculates and prints out the minimum value of the array. – Write a loop that calculates and prints out the maximum value of the array. – Write a loop that calculates and prints out the average value of the array.
(Data processing) A bank’s customer records are to be stored in a file and read into a set of arrays so that a customer’s record can be accessed randomly by account number. Create the file by entering five customer records, with each record consisting of an integer account number (starting with account number 1000), a first name (maximum of 10 characters), a last name (maximum of 15 characters), and a double-precision number for the account balance. After the file is created, write a C++ program that requests a user-input account number and displays the corresponding name and account balance from the file.

Task related to pointers : Write a c++ program that asks the user to enter integers as inputs to be stored in the variables 'a' and 'b' respectively. There are also two integer pointers named ptrA and ptrB. Assign the values of 'a' and 'b' to ptrA and ptrB respectively, and display them. ( Drop code in words , explain the code and drop the screenshot of output as well )
C++ Create a class Student that contains three members: roll no, name and mark, and three functions. Write a first inputStudent() function to get data of student class. Write a second getMark() function that returns a student’s mark. Write a third display() function that displays a student’s data. In a main() function, you need to declare 40 students and get data of all students by using inputStudent() function. And also use a pointer array to keep all students by mark greater than 50 and display the searching data of each student in that pointer array (Use the access operator -> to access a pointer points to member functions of the Student class).
Objective:Design and implement a word unscrambler game in Java.Details:Your program should read in a random word from a file called words.txt (note the lack of capitalization) that you provide. There should not be any hard limit on the number of words in the file. If words were added/removed from the file, your program should recognize such changes of the words.txt and handle appropriately next time it runs. The file should contain one word per line. To read a random word you can generate a random number between 1 and the number of lines, and skip n-1 lines before reading the word. Scramble the word by swapping random pairs of letters a random number of times. Display the scrambled word with character indexes on top. Assume that the word is always no more than ten characters (so that index can be within 0-9 range, inclusive).Offer the user a menu with the following choices:• Enter 1 to swap a pair of lettersIf this option is selected prompt the user to enter two indexes and swap the…
