This lesson is on how to use pointers instead of member variables in a class.  I keep getting compile errors that i do not understand.  The latest is "Error 1 general error c1010070: Failed to load and parse the manifest. The system cannot find the file specified. .\Debug\Week6ex2.exe.intermediate.manifest" 
Also I had a c2228 left of .length must be a class/struct/union .

Help in any way would be greatly helpful:)
