OLittleO (54)
So I am pretty sure what I am doing is right but it keeps giving me an error so idk if I a missing a header? or I am doing it wrong and thinking its right. So here is my code. This is the error i get
||In function 'void getRatings(int (*)[6])':|
|58|warning: extended initializer lists only available with -std=c++0x or -std=gnu++0x||58|error: cannot convert '<brace-enclosed initializer list>' to 'int' in assignment|

You can't assign values to array elements using brackets, unless you do it as initialization. Line 16 is correct because you just created the array and you are initilizing it. in getRatings() you're assigning a new value and that's forbidden, you have to use a loop or insert them manually

C++11 introduced support to initiliaze std containers using brackets, but I don't know if it extends arrays capabilities too

Can i insert them manually one by one?( like reviews[1][1]= 3) or do i have to have the user do it?

You can insert them manually but it's not really smart. Why don't you just put the initializer list in line 16?

Not really sure my teacher gave us a sample outline with and I was following his functions even though he said we could do it however we want I think the instructions state you make use the follow outline bellow or create your own
