This is a really simple program but for the life of me i do not know why it is not working. When trying to compile I recieve these errors.
‘int main()’:
main.cpp:9:11: error: no matching function for call to ‘GenShape::GenShape()’
main.cpp:9:11: note: candidates are:
In file included from main.cpp:1:0:
GenShape.h:15:3: note: GenShape::GenShape(int)
GenShape.h:15:3: note: candidate expects 1 argument, 0 provided
GenShape.h:8:7: note: GenShape::GenShape(const GenShape&)

You forgot to define the default constructor GenShape::GenShape() in the cpp module.
