/*定义一个类来表示银行账户。数据成员包括储户姓名、账号（使用字符串）和存款。成员函数执行如下操作：

对象初始化；

2）显示储户姓名、账号和存款；

3）存入参数指定的存款；

4）取出参数制定的款项。

请提供类声明及类的实现。并编写主函数进行测试。*/

int main()

{

 using namespace std;

 BankAccount acc1("heyyroup","286962249",14000);

 acc1.show();

 acc1.fetch(1200);

 acc1.show();

 acc1.saving(4200);

 acc1.show();

 BankAccount acc2=BankAccount("sunshineradio","32012088",2000);

 acc2.show();

 acc2.fetch(4300);

 acc2.saving(-7);

 return 0;

}

一.  BankAccount(char *Name="none",char *Number=0,double Balance=0.0);

改为

BankAccount(const char *Name="none",const char *Number="0",double Balance=0.0); //你的Number是字串型,不能赋为0的 ,另外改为const更合理(非必须) 

二.BankAccount::BankAccount(char *Name/* ="none" */,char *Num/* =0 */,double Bal/* =0.0 */)

改为

BankAccount::BankAccount(const char *Name/* ="none" */,const char *Num/* =0 */,double Bal/* =0.0 */) //与上面对应 

三.BankAccount::BankAccount中的内容改

strcpy(this->Name,Name); //你要区分两个Name的,最好不用同一名字,另外不用strncpy的,用这个中间数据要乱的 

//Name[49]='';

strcpy(Number,Num); //与上同理 

//Number[24]='';

Balance=Bal;

运行结果
