I recently added classes to my practice code and I get 3 errors, I have checked through my book and can't find why I get the errors. It's probably a really noobie mistake but it's driving me crazy.
The errors are
error C2628: 'test' followed by 'int' is illegal (did you forget a ';'?)
error C2556: 'test test::testx(int)' : overloaded function differs only by return type from 'int test::testx(int)'
: see declaration of 'test::testx'
: error C2371: 'test::testx' : redefinition; different basic types
: see declaration of 'test::testx'
and the code is
thx in advance
You are missing a semicolon after your declaration of class "test":
class Name { // stuff}; <-- here
Biggest newbie mistake was stripping out the line numbers for those error messages.}; <--- this is missing at the end of the class definitionint test::testx(int i) <--- where the (nonsensical) errors start --- in other words, where the compiler has gotten confusedThere are other errors reported by VS2005 after fixing this one, but these are obvious and easily fixed.

After I fixed it it turned out that a had no value.
After a few mins of moving around of code I came to an end result.
thx again [lol]
