c ++错误：私人期望a;

Question

我的头文件中的Private类出错了。它说＆＃34;期待一个;＆＃34;。任何帮助都会受到赞赏，因为我是c ++的新手。

部首：

#ifndef CONEMODEL2
#define CONEMODEL2



#include <iostream>
#include <string.h>


using namespace std;
class Cone
{

public:
Cone(void);
Cone(double aLength, double aBigRadius, double aSmallRadius, double  aHeight);
~Cone();
void setCone(double aLength, double aBigRadius, double aSmallRadius, double aHeight)
double getCone(void);
double calculateArea();
double calculateVoume();
double displayTheArea();
double displayTheVolume();


private:
double theLength;
double theHeight;
double bigRadius;
double smallRadius;


};

简单的拼写错误：

void setCone(double aLength, double aBigRadius, double aSmallRadius, double aHeight);
//                                                                       Semicolon! ^
