帮我找以下c++代码的bug：#include<iostream> #include<cstring> using namespace std; class Employee { private: long num; string name; char sex[4]; const char* sect; int wage; static int count; static long totalWage; public: Employee(long n,string nam,char se[4],const char* sec,int wag); void print(); static void ShowStatic(); }; Employee::Employee (long n,string nam,char se[4],const char* sec,int wag) { num=n; name=nam; strcpy(sex,se); sect=new char[strlen(sec)+1]; strcpy(sect,sec); wage=wag; count++; totalWage+=wag; } void Employee::ShowStatic() { cout<<count<<" "<<totalWage<<endl; } void Employee::print() { cout<<num<<" "<<name<<" "<<sex[4]<<" "<<sect<<" "<<wage<<endl; } int main () { int count=0; long totalWage=0; Employee a[2]={Employee(123,"dsb","nan","bzd",2023),Employee(234,"xsb","nv","bzd",2024)}; a[0].print(); a[1].print(); a[0].ShowStatic(); return 0; }

在类定义中，静态数据成员 count 和 totalWage 必须在类外进行初始化。

在 main 函数中，变量 count 和 totalWage 与类中的同名静态数据成员重名，造成了混淆。

以下是修正后的代码：

#include<iostream>
#include<cstring>
using namespace std;

class Employee {
private:
    long num;
    string name;
    char sex[4];
    const char* sect;
    int wage;
    static int count;
    static long totalWage;
public:
    Employee(long n,string nam,char se[4],const char* sec,int wag);
    void print();
    static void ShowStatic();
};

int Employee::count = 0;  // 静态数据成员初始化
long Employee::totalWage = 0;

Employee::Employee (long n,string nam,char se[4],const char* sec,int wag) {
    num=n;
    name=nam;
    strcpy(sex,se);
    sect=new char[strlen(sec)+1];
    strcpy(sect,sec);
    wage=wag;
    count++;
    totalWage+=wag;
}

void Employee::ShowStatic() {
    cout<<count<<" "<<totalWage<<endl;
}

void Employee::print() {
    cout<<num<<" "<<name<<" "<<sex<<" "<<sect<<" "<<wage<<endl;
}

int main () {
    Employee a[2]={Employee(123,"dsb","nan","bzd",2023),Employee(234,"xsb","nv","bzd",2024)};
    a[0].print();
    a[1].print();
    Employee::ShowStatic();  // 静态成员函数调用
    return 0;
}

修改后的代码中，静态数据成员 count 和 totalWage 在类外进行初始化，避免了混淆。在 main 函数中，使用 Employee::ShowStatic() 调用静态成员函数。
