C + + header file The class declaration after forgetting to add a semicolon produces an unexpected compilation error

The contents of the header file Test.h are

class Test
{
public:
virtual void test1();　
}

The implementation file is

Test.cpp
#include "Test.h"
#include <iostream>
using namespace std;
void Test::test1(){　cout<<"Hello"<<endl; }

An error occurred at compile time

c:\program files\microsoft visual studio\vc98 \include\errno.h(29) : error C2143: syntax error : missing ';' before 'string'
c:\program files\microsoft visual studio\vc98\include\errno.h(29) : fatal error C1004: unexpected end of file found

Do not connect these two files to consider it is difficult to know is there is wrong, and Unmi originally write Java is much more than C + +, Java can not #include usage, in fact, have C + + experience, understand the #include只是把被包含文件的内容引入到当前位置.

The above inserts the contents of the Test.h into the Test.cpp file #include "Test.h", it should be noted that the class declaration must be followed by a semicolon, you can take the class declaration as a normal variable declaration statement, need to end a semicolon, or there will be many unpredictable compilation errors

The type of error is not just the above, the main content of the document introduced to the current position, and then the statement difference between a semicolon will be a syntax error, so you should form a class declaration after the good habit will not be wrong.

such as the implementation of the file written

#include "Test.h"
void Test::test1(){}

The mistake that comes up is

#include "Test.h"
void Test::test1 () {}

Projects\testvirtual\test.cpp (3): Error C2628: ' Test ' followed by

redefinition different basic types

Because the compiler sees no semicolon between the class declaration of the header file and the statement void Test::test1 () {}.
