header files error

[praneshiitm]

i am making a program in which there are a no of classes which i have declared in some header files and then i have included them in the main program but it is showing some errors....the names of the header files are:

#include"Header.h"
#include"int2string.h"
template <class T>
#include"categories.h"
#include"Player.h"
#include"QnA.h"
#include"Scoremanager.h"
#include"wait.h" 

and the errors are :

can someone tell me what could be wrong because my visual studio is not showing any red underlines below any line but on compiling these errors come up.

Missed a semicolon at the end of a class declaration didn't ya? No worries, it happens to me from time to time as well.

no...i didn't miss the semicolon...actually i didn't write 'using namespace std;'
in the header files....
i wrote that and its done...
