Assignment Write a program that reads a 2D array of chars, checks, and corrects each char within this array, and print out the corrected 2D array. First the program will read the row count (rowCount) and column count (columnCount) of the 2D array, both as int values. Then, the chars constituting the 2D array will be read on a row-by-row basis. After reading the 2D array, the program will check and correct each char within the 2D array according to the rules below. This process MUST be done by using a void function by sending the appropriate cell of the 2D array with a call-by-reference fashion. • If the row index is an even number, a char can only be a lowercase English value. • If the row index is an odd number, a char can only be ?, 7', or X'. • Any incorrect value MUST be changed into Finally, the checked and corrected 2D array will be printed out to the screen. NOTE: Checking the correctness of a char and correcting it (if necessary) MUST be done in the function with a…
Write VBA CODE FOR THE FOLLOWING PROBLEM Problem: The Worksheet named Grades contains a place for students to record the grades they have received in their classes. Students put the number of each letter grade received in the B column. (For example, the worksheet currently shows that the student has taken 9 classes and made five As, one B, one C, one D, and one F as grades. You need to write a program that reads the grades from the worksheet and uses a function to calculate the student’s GPA. For this problem you can assume that all classes are worth the same number of credit hours. The function should send back the GPA to the calling procedure. The procedure will then put up a message box that gives the student their GPA and a message about their GPA, all in one message box. The message should be “You qualify for an internship” if the student has a GPA of at least 3.0. It should be “You’re in the danger zone” if the GPA is between 2.0 and 3.0. And it should be “You are on…

Programming Language: C++ You have been hired by Google to work on their YouTube videos search team. Every YouTube video has a unique ID and those IDs are in unsorted order. As a software engineer, you are required to make a YouTube search engine which works for very user. Create a test engine that only holds seven YouTube IDs. Prompt for and get from the user the seven IDs and store them in an integer array. Then sort and print the array using the insertion sort algorithm. Finally, use a sentinel loop to prompt for and get from the user a series of IDs. For each ID, perform a binary search on the array and tell the user if it was found or not. If found, print the index where the ID is stored. Continue to prompt the user for an ID until entering the sentinel value of -999. In addition to function main, define the following two functions: void insertion_sort(int arr[], int arr_size) int binary_search(int sort_arr[], int size_array, int search_value) binary_seacrh returns…

For C++: Design an application that has an array of at least 20 integers. It should call a module that uses the sequential search algorithm to locate one of the values. The module should keep a count of the number of comparisons it makes until it finds the value. Then the program should call another module that uses the binary search algorithm to locate the same value. It should also keep a count of the number of comparisons it makes. Display these values on the screen.
