In your DisplayDetails() function, you take an array of "Custs" as an arguement:
but then you have record.rent. I don't think you can do that since record is an array. Try indexing it like you did with the others:
or remove your brackets from the arguement being taken.

Also, try to post only the code that is relevant to your problem.

Strictly speaking that syntax in a function declaration/definition indicates a pointer not an array. Normally it would be used (it at all) if the pointer was in fact a pointer to the first element of any array (i.e. a pointer to an array by convention rather than by language rules) but it is functionally equivalent to (and interchangeable with)
