Editing data

[FranciscoDiaz]

I am writing a program that will allow a user to edit hard coded data from an array. my issue is I don't know how to get the information to be saved and not just reset once the function has been exited.

Lines 108 - 110 need to be static. Right now, every time you enter the function, these variables get created and populated. If you want the values to maintain their values over multiple function calls, you need to declare the variables as static.

static double boxPrice[]={9.99, 9.99, 6.99, 7.99, 15.50};

Thank you

[FranciscoDiaz]

i have one more issue
its telling me that my function void makePurchase is overloaded i dont know why ive only created one prototype and only called it once;

the issue only arises when i try to pass

static double boxPrice[]={9.99, 9.99, 6.99, 7.99, 15.50};
