Error in VC++ for code that looks perfectly good C++?

Hey guys. Check out this piece of sample code.

#include "stdafx.h"
#include<conio.h>
#include<string.h>

class person{
private char name[20];
private int age;

public void setValu开发者_运维问答es(char n[],int a)
{
    strcpy(this->name,n);
    this->age=a;
}
public void display()
{
    printf("\nName = %s",name);
    printf("\nAge = %d",age);
}
};


int _tmain(int argc, _TCHAR* argv[])
{
person p;
p.setValues("ram",20);
p.display();
getch();
return 0;
}

I am getting the following errors :

The syntax of declaring public and private is wrong. Unlike other languages, in C++ it should be

class person{
private: 
char name[20];
 int age;
public:
  void display();

....


In C++, private works like this:

class A 
{
private:
    void f();
    void g();
};

Note the colon.
