Part of your problem is that you have 6 members of the cd_detail struct (group, name, year, price, playtime, and costTotal), but you're only initializing 5 of them.

{"Alan","I love China",2010,53,500} //only 5 values here...

The value that you are failing to initialize is the value of costTotal.
The other part of your problem is likely that you are not dereferencing the array element(s) correctly. You should really rewrite your access statements as


Notice the parentheses...

Or am I misunderstanding what your problem is?

To Fbody: array[index].member will work too. Although I did not really get the problem.


It depends on how the array is declared. For this situation, it should be fine, because you only have one level of pointer indirection. But, if the array contained pointers, there would be an issue because the levels of indirection wouldn't dereference in the correct order.

In My Opinion, it's better to be consistently explicit than it is to wind up with an extremely insidious intent error because your situation changed.
