例1-2 get函数返回私有变量指针有问题吗

#include<iostream>
#include<cstring>
using namespace std;
class Account{
    private:
        int ID;
        char Name[20];
        float balance;
    public:
        void Initial(int ID,char Name[],float balance);
        int withdraw(float m);
        void deposits(float m);
        char *getname(){
            return Name;
        } 
        void setName(char*name){
            strcpy(Name,name);
        }
        void showme(){
            cout<<Name<<" "<<balance<<endl;
        }
}; 
void Account::Initial(int ID,char Name[],float balance)
{
    this->ID=ID;//因为名称相同,所以要用this指针来访问 
    strcpy(this->Name,Name);
    this->balance=balance;
}
int Account::withdraw(float m)
{
    if(balance>m){balance=balance-m;return 1;}
    else return -1;
}
void Account::deposits(float m)
{
    balance=balance+m;
}
int main()
{
    Account my,other;
    char name[]="Jack";
    my.Initial(10112,name,600.0);
    my.withdraw(500.0);
    my.showme();
    char*p=my.getname();//获取了私有变量的指针 
    strcpy(p,"abc");//直接0修改了私有变量的内容 
    my.showme();
    return 0; 
}
