Have a look at arrays in C++ in general: http://www.cplusplus.com/doc/tutorial/arrays/

Anyway in principe your code should work if you add '[]' after values in your function, or put '*' in front of it. After that you can simply do values[3]=2; for example. Do take into account C(++) doesnt know how long your array is, if you write values[10] = 0;, it will simply clear out a bunch of bytes in a certain location, which is not what you want.
