For one of my options, I had to add a row of data to my struct array, I was able to update the array but it does not update the actual array. So I am trying to update my struct array by passing it as a reference. I placed the '&' sign before the name of the variable, but all my indexes within the function errored.. I'm still a newbie to programing and I'm not "allowed " to use any vectors according to my Professor. . I looked online and placed the '&' on the function name as well as on the prototype. I also changed it from void to the "data type" to return the updated array, but no luck... I hope this comes out clear....
