大佬，再帮我这个渣改下c++的题
/*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。*/
#include <iostream>
#include <cstring>
class BankAccount
{
private:
char Name[50];
char Number[25];
double Balance;
public:
BankAccount(char *Name="none",char *Number=0,double Balance=0.0);
void saving(double money);
void fetch(double money);
void show()const;
};
BankAccount::BankAccount(char *Name/* ="none" */,char *Num/* =0 */,double Bal/* =0.0 */)
{
strncpy(Name,Name,49);
Name[49]=' ';
strncpy(Number,Num,24);
Number[24]=' ';
Balance=Bal;
}
void BankAccount::saving(double money)
{
if (money<0)
{
std::cerr<<"The saving money can't be negative"
<<", Transation is terminate"<<std::endl;
}
else
Balance+=money;
}
void BankAccount::fetch(double money)
{
if (money>Balance)
{
std::cerr<<"There isn't enough money in your account!!!"<<std::endl;
}
else if (money<0)
{
std::cerr<<"The money can't be nagative!"<<std::endl;
}
else
Balance-=money;
}
void BankAccount::show() const
{
using std::cout;
using std::endl;
cout<<"Client : "<< Name<<endl
<<"Account : "<< Number<<endl
<<"Balance : "<< Balance<<endl;
}
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
