Thanks.

The particular error message you got ("Access violation writing location
0xe7430e45") suggests to me that scanf is trying to write to a pointer
you gave it but the pointer is wrong.  Can you find out which pointer
has the value 0xe7430e45?  Use printf("%p"...) to print the values of
the pointers n, r and scanString in getData().

It's possible that you are not passing the arguments on the stack in the
correct order.  If that's the case, scanf will be looking at one of the
integer pointers as a string, and anything could happen.  Try reversing
the order of the arguments on the stack.
