Extracted text: Course Management Teaching Assesment ePortfolio Mahara Course search Helpdesk Develop a C++ program to calculate the area, perimeter and diagonal of a rectangle. The program should also offer the option to display the rectangle. The main flow of the program is given as follows: red 20.00 The user should input the length and width of a rectangle. The user can decide to display the drawing of the rectangle or not. If user indicate yes, execute user's decision. • Display the calculated area, perimeter and diagonal of the rectangle. The program should repeatedly ask if the user wants to process another rectan- gle. Your program should include two functions with the following function prototypes: void drawRec(int length, int width); A function that display a full rectangle with +'. void calcRec (int a, int b, int area, int perim, float diag); A function that returns the area, perimeter and diagonal through pointer parame- ter. Sample output: Enter the length and width of a rectangle: 4 8
