Declaration is incompatible with type
提问by Eric Oudin
header file:
头文件：
#ifndef H_bankAccount;
#define H_bankAccount;
class bankAccount
{
public:
string getAcctOwnersName() const;
int getAcctNum() const;
double getBalance() const;
virtual void print() const;
void setAcctOwnersName(string);
void setAcctNum(int);
void setBalance(double);
virtual void deposit(double)=0;
virtual void withdraw(double)=0;
virtual void getMonthlyStatement()=0;
virtual void writeCheck() = 0;
private:
string acctOwnersName;
int acctNum;
double acctBalance;
};
#endif

cpp文件：
#include "bankAccount.h"
#include <string>
#include <iostream>
using std::string;
string bankAccount::getAcctOwnersName() const
{
return acctOwnersName;
}
int bankAccount::getAcctNum() const
{
return acctNum;
}
double bankAccount::getBalance() const
{
return acctBalance;
}
void bankAccount::setAcctOwnersName(string name)
{
acctOwnersName=name;
}
void bankAccount::setAcctNum(int num)
{
acctNum=num;
}
void bankAccount::setBalance(double b)
{
acctBalance=b;
}
void bankAccount::print() const
{
std::cout << "Name on Account: " << getAcctOwnersName() << std::endl;
std::cout << "Account Id: " << getAcctNum() << std::endl;
std::cout << "Balance: " << getBalance() << std::endl;
}
Please help i get an error under getAcctOwnersName, and setAcctOwnersName stating that the declaration is incompatible with "< error-type > bankAccount::getAcctOwnersName() const".
请帮助我在 getAcctOwnersName 和 setAcctOwnersName 下获得错误，指出声明与“<错误类型> bankAccount::getAcctOwnersName() const”不兼容。

You need to
你需要
#include <string>
in your bankAccountheader file, and refer to the strings as std::string.
在您的bankAccount头文件中，并将字符串称为std::string.
#ifndef H_bankAccount;
#define H_bankAccount;
#include <string>
class bankAccount
{
public:
std::string getAcctOwnersName() const;
....
once it is included in the header, you no longer need to include it in the implementation file.
一旦它包含在标题中，您就不再需要将它包含在实现文件中。
