c++ - Problem with "not declared in this scope" error -

I have found:

Error not declared in this area

Can anyone explain why this code is the reason?

quiz.h

  #ifndef QUIZ_H_ # Define QUIZ_H_ #include "quiz.cpp" // I removed this line // and deleted the quote quote (int i ) Written; Class A {Private: integer player; Public: A (Intuitplayer); // written here = 0 ~ A (); Zero foo (); }; #endif / * QUIZ_H_ * /  

Quiz CPP

  #include "quiz.h" #include & lt; Iostream & gt; Using std :: cout; Using the Std :: endl; A: A (int plateer = 0) {// deleted = 0 player = initPlayer; } A: ~ A () {} Zero A: Fu () {cout & lt; & Lt; Player; }  

main function

  #include "quiz.h" int main () {quiz (7); Return 0; }  

quiz function

  #include "quiz.h" zero quiz (int i) {a a1 (i); A1.foo (); }  

After my modifications I have several definitions of an error quiz (en)

You should not include the .cpp file in the header. Remove:

  #include "quiz.cpp"  

Additionally, the default value in:

  A :: AE (at leastplayer = 0) { 

) should be in the header file instead.

And edit your question All your files, we will tell you how to compile and link them.
