大家好，我是c++新手，有些不懂的地方想请教一下

#include "stdio.h"

class CBook
{
public:
    char m_BookName[128];
    const unsigned int m_Price;
    int m_ChapterNum;
    CBook()
        :m_Price(32),m_ChapterNum(15)
    {
        strcpy(m_BookName,"大学英语");
        printf("构造函数被调用\n");
    }
    CBook(const CBook &book)
        :m_Price(book.m_Price)
    {
        m_ChapterNume=book.m_ChapterNum;
        strcpy(m_BookName,book.m_BookName);
        printf("复制构造函数被调用\n");
    }
}
void OutputBookInfo(CBook book)
{
    printf("%s\n",book.m_BookName);
}
int main(int argc,char* argv[])
{
    CBook book;
    OutputBookInfo(book);
    return 0;
}



运行出错！
老是提示这个错误：'CBook' followed by 'void' is illegal (did you forget a ';'?)
高人指点下。谢谢了！
