when adding a pointer in any main body like a inventory displayer , does it matter about the order of placement? Is it necessary to have " return 0;" at the end of it if or is it included with original maroon body? thanks in advance!

Write a program that uses a dynamic array that contains 5 items of double values. The size of the array is entered when the program is run. Aldo the 5 values must be entered. These tasks are done in the main ( ) function. Then write a function to display the 5 values. The function must have a pointer variable as a parameter. The function is called from the main ( ).
