c++:没有重载函数的实例

Question

highInterestChecking header :

#ifndef H_highInterestChecking
#define H_highInterestChecking
#include "noservicechargechecking.h"
#include <string>

class highInterestChecking: public noServiceChargeChecking
{
public:
    highInterestChecking(std::string =" ",int = 0, double = 0.00, double = 0.00, double = 0.00);
};
#endif

highInterestChecking cpp:

#include "highInterestChecking.h"
using std::string;

highInterestChecking::highInterestChecking(string name, int acct, double bal, int numCheck, double min, double i)
{
    bankAccount::setAcctOwnersName(name);
    bankAccount::setAcctNum(acct);
    bankAccount::setBalance(bal);
    checkingAccount::setChecks(numCheck);
    noServiceChargeChecking::setMinBalance(min);
    noServiceChargeChecking::setInterestRate(i);
}

我遇到错误“没有重载函数的实例”。在 cpp 文件中的构造函数名称 highInterestChecking 下不确定是什么原因导致它我看了一段时间现在似乎找不到错误。也许有人会帮忙？

在标题中你有:

highInterestChecking(std::string =" ",int = 0, double = 0.00, double = 0.00, double = 0.00);

需要 5 个参数，在源文件中你有:

 highInterestChecking::highInterestChecking(string name, int acct, double bal, int numCheck, double min, double i)

                                                                                ^^^^^^^^^^^

它接受 6 个参数。似乎 int numCheck 与 header 签名不匹配。
