Q1 write C++code that ask the user to enter a number and the program will generate matrix K (4 by 4 matrix) and the chosen number will be the first element of that matrix. After that, the user will chose one of the following functions: 1) Swap function: the code will swap the elements of the secondary diagonal with the element of the main diagonal. 2) Multiply by 3: the program willl multiply the matrix by 3. 3) Exit : the program will exit.

C++

c++ program write a recursive function to find the factorial of a number. main points : 1) n and r are stored in two parallel arrays.  2) you have to read the arrays n and r at run time. 3) compute nCr for each corresponding terms in the array n and r and display it properly formatted  4) also in the program you should print the current date and time using the library functions

C++ Do the following lab by an array(not vector) for 3 students find the average of a student by asking him how many grades do you have. The answer to this question, determine the size of the array(list of grades) and then ask the user to enter grades(the number of the grades is equal to the size of the array) then calculate the average for each student. Hence, you will calculate 3 averages. to calculate the average, use the array accumulator. Also when you get each grade validate it. validation for grade means that you check whether a grade is between 0 and 100. if the grade is negative or a grade is more than 100 then it is not valid and you have to ask the user to enter a grade again. Find the maximum and minimum grades for each student. Print the sorted list of the grades for each student. example: if grades user entered are: 60 78 98 23 45 then sorted list is:23 45 60 78 98

C++ This program will store roster and rating information for a soccer team. Coaches rate players during tryouts to ensure a balanced team. (1) Prompt the user to input five pairs of numbers: A player's jersey number (0 - 99) and the player's rating (1 - 9). Store the jersey numbers in one int vector and the ratings in another int vector. Output these vectors (i.e., output the roster). Ex: Enter player 1's jersey number: 84 Enter player 1's rating: 7 Enter player 2's jersey number: 23 Enter player 2's rating: 4 Enter player 3's jersey number: 4 Enter player 3's rating: 5 Enter player 4's jersey number: 30 Enter player 4's rating: 2 Enter player 5's jersey number: 66 Enter player 5's rating: 9 ROSTER Player 1 -- Jersey number: 84, Rating: 7 Player 2 -- Jersey number: 23, Rating: 4 ... (2) Implement a menu of options for a user to modify the roster. Each option is represented by a single character. Following the initial 5 players' input and roster output, the program outputs the menu.…

C++   Write the program that outputs the following menu.  The program should allow a user to input numbers into an array of integers.  The array size should be 10.  The first number should be stored in the zero position of the array.  The next number should be stored in the next available location.  Each option below should be written using a procedure, except Quit.   Remember to comment the procedures with (given, task and return). (MENU) 1)    Input number. 2)    Sort numbers. 3)    Output numbers 4)    Quit Option 1)  Allows the user to input a number and store it into the array.  If the array is full no more numbers should be input.  When the user select option 1 and the array is full it should output (Memory Full!).  This option will only allow one number to be entered.  If the user want to input another number they will need to select option 1 again. Option 2)    This option should take the array and sort it in ascending order.  Use the selection sort to do this. Option 3)…

use c++ Programming language  Write a program that creates a two dimensional array initialized with test data.  Use any data type you wish .  The program should have following functions: .getAverage: This function should accept a two dimensional array as its argument and return the average of each row (each student have their average) and each column (class test average) all the values in the array. .getRowTotal: This function should accept a two dimensional array as its first argument and an integer as its second argument.  The second argument should be the subscript of a row in the array. The function should return the total of the values in the specified row. .getColumnTotal:  This function should accept a two dimensional array as its first argument and an integer as its second argument.  The second argument should be the subscript of a column in the array. The function should return the total of the values in the specified column. .getHighestInRow: This function should accept a two…
