Q2) Write a function that calculates and displays the sum of on-diagonal elements and the sum of lower triangle elements. Also print the elements of matrix A. The following is the matrix: int A[3][3] = {{ 20, 13, 10}, {15, 15, 13}, {20, 24, 60}}; Sum of on-diagonal elements = 95 Sum of lower triangle elements = 59 void Diagonal(int A[][3], int &Ondiag, int &lowTri, int size);

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

How do you put a 2D array code into a function? (C++ only)

need help in C++ Problem: You are asked to create a program for storing the catalog of movies at a DVD store using functions, files, and user-defined structures. The program should let the user read the movie through the file, add, remove, and output movies to the file. For this assignment, you must store the information about the movies in the catalog using a single vector. The vector's data type is a user-defined structure that you must define on functions.h following these rules: Identifier for the user-define structure: movie. Member variables of the structure "movie": name (string), year (int), and genre (string). Note: you must use the identifiers presented before when defining the user-defined structure. Your solution will NOT pass the unit test cases if you do not follow the instructions presented above. The main function is provided (you need to modify the code of the main function to call the user-defined functions described below). The following user-defined functions are...
