As a beginner, this leaves me dumbfounded.

First off, please use code tags (not output) so we can read the code better ;)

Second, start with one error at a time. When you see a big mess of output like this you can get
discouraged quickly. Go down the list, read the error codes. For example your first concern is:
error C2664: 'SetConsoleTitleW' : cannot convert parameter 1 from 'const char [17]' to 'LPCWSTR'


Lookup C2664 on google if you can't figure out what went wrong.

I'm not saying this to be annoying, but this is how we all learn ;)

Thanks for the advice. I'll try to resolve these errors >.<.

Edit: I fixed the code tags.

Dont make a program that makes readme.txt. People obviously want to read it before using the program.

I fixed all of the errors. Here is the revised code if anyone would like to see it. =)
