Question

I’m getting this compilation error with the following code:

error C2143: syntax error : missing ‘;’ before ‘using’

#include <iostream>
#include <iomanip>
#include <fstream>
#include <string>
#include "s.h"

using namespace std;

How is this possible? How can it be fixed?

Answer 1

"s.h" might contain a class declaration that wasn’t terminated with a ;

When you include a header, the C preprocessor puts substitutes header’s contents in in-line, so if you look at s.h you will probably find something unterminated by ;
