Write a C program that, 1. writes an n x n matrix into a file named "matrix.txt" the matrix has to contain the number as it is given in the example, and n has to be given by the user 2. contains a function with the name "averageM", which o input parameters are the main diagonal (in the example: [0,1,3]) o of the matrix and the size of the main diagonal (in the example: 3) o and returns with the average of the numbers in the main diagonal (in the example: 1.33) 1. calls the "averageM" function on the matrix.txt" and displays the result on the screen Instruction for the user: "n=": Example: Input: 3 Output in the file: 001 112 223 Output on the screen: 1.33

Help me structure a program in C++ that opens a file for read. Then reads the data in from the file and calculates the sum of the row values. The data is all integers with 7 values per line, and 10 lines of data in the file. The program must use two functions, one to open the file, and another to output and calculate the sum of the row values. All data must be read into a two dimensional array first, then the data is output and the sum calculated. The data should be printed out by row, along with the sum of the row values. Prototypes to be used: void rowSumCalculator( int myArray[][10], int rowCount, int colCount );Function rowSumCalculator( ) writes out the data in the array and the sum of the values in the row. void openFile( ifstream& infile, string prompt );Function openFile should print the prompt out to the user, read in the filename and open the file. If the file does not open, an error is written to the display, and the user prompted again. The function doesnot return until…

Write a program that reads movie data from a CSV (comma separated values) file and output the data in a formatted table. The program first reads the name of the CSV file from the user. The program then reads the CSV file and outputs the contents according to the following requirements: Each row contains the title, rating, and all showtimes of a unique movie. A space is placed before and after each vertical separator ('|') in each row. Column 1 displays the movie titles and is left justified with a minimum of 44 characters. If the movie title has more than 44 characters, output the first 44 characters only. Column 2 displays the movie ratings and is right justified with a minimum of 5 characters. Column 3 displays all the showtimes of the same movie, separated by a space. Each row of the CSV file contains the showtime, title, and rating of a movie. Assume data of the same movie are grouped in consecutive rows. Hints: Use the find() function to find the index of a comma in each row of…

In C++, define an integer vector and ask the user to give you values for the vector. Because you used a vector, so you don't need to know the size. user should be able to enter a number until he wants(you can use while loop for termination. for example if the user enters any negative number, but until he enters a positive number, your program should read and push it inside of the vector). the calculate the average of all numbers he entered.
