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 ( ).

In the short code below, I declared an array of five elements. But I'm getting confused on how to use it in a while loop. My main question is , if the user inputs a userchoice1 value that is less than 1, I want the code to keep looping until the user inputs a number that is not less than 1. But I don't know if the 7th line (userchoice1 [x]++) shows the right way to loop it.
