我正在使用代码块v16 *
我收到了这个错误,我无法弄清楚似乎是什么问题:
Person.cpp:17:62:注意:不匹配的类型'const std :: basic_string< _CharT,_Traits,_Alloc>'和'void' std :: cout<< “出生日期:”<< BirthdateObj.showBirthDate(); ^ 处理终止,状态为1(0分钟,0秒(秒)) 1个错误,0个警告(0分钟,0秒(s))
这是我的简单程序:
Person.h
#include "Birthdate.h"
#include <iostream>
Birthdate::Birthdate(int day, int month, int year) : day(day), month(month), year(year)
{
//ctor
}
Birthdate::~Birthdate()
{
//dtor
}
void Birthdate::showBirthDate()
{
std::cout << day << "/" << month << "/" << year;
}
Person.cpp
#include <iostream>
#include "Birthdate.h"
#include "Person.h"
int main()
{
Birthdate BirthdateObj(7, 16, 1995);
//Birthdate *pBirthdateObj = &BirthdateObj;
Person PersonObj(20, BirthdateObj);
Person *pPersonObj = &PersonObj;
pPersonObj->showPersonInformation();
//pBirthdateObj->showBirthDate();
return 0;
}
Birthdate.h

Birthdate.cpp
def set_latlon(lat, lng)
factory = RGeo::Geographic.spherical_factory(srid: 4326)
# NOTE: this method takes the LNG parameter first!
self.latlon = factory.point(lng, lat)
end
的main.cpp
:point
答案 0 :(得分:0)
您的生日功能会返回void
而不是string
。由于cout
无法将void
输出到标准输出,因此这就是您的错误所在。改变这一行:
std::cout << "Birthdate: " << BirthdateObj.showBirthDate();
为:
std::cout << "Birthdate: ";
BirthdateObj.showBirthDate();
或者,您可以将showBirthdate
的返回类型更改为string
,并按原样保留上述行。
