Create a function called "ResizeArray" to be used whenever the number of items to be added to ShoppingCart would exceed the current bounds of the array. This function must return void. The user should not be aware that the size of the array is changing. Rather, s/he should simply be allowed to keep adding items until s/he is done, and ResizeArray should be called (transparently to the user) whenever the number of items to be added would exceed the bounds of the array so that the user may add as many items as s/he likes. Each call to ResizeArray should double the size of the existing ShoppingCart. If by any chance all heap memory is exhausted, an appropriate error message should be issued to the user. Make sure you test your function by adding more items than originally requested at the start of your program.
