新手：C++出现 “People::getAnswer”: 非标准语法；请使用 "&" 来创建

[qq_41647611]

class People
{
private:int myweight;
double myheight;
double mybmi;
public:
People() :myweight(0), myheight(0.0), mybmi(0.0){}
People(int weight,double height):myweight(weight),myheight(height){}
void calculatebmi() { mybmi= myweight / myheight * myheight; }
void getAnswer(){
calculatebmi();
if (mybmi > 23.9)cout << "Yes!" << endl;
else cout << "No！" << endl;
}
};

请问应该怎样修改我的代码呢？
谢谢各位大佬了

没看懂问什么.... People::getAnswer() 这种方式只有 static 声明的才可以直接调用吧 否则只能通过对象调用

那请问我应该怎么样修改呢？

给出完整代码....

[qq_41647611]

#include <iostream> using namespace std; class People { private:int myweight; double myheight; double mybmi; public: People() :myweight(0), myheight(0.0), mybmi(0.0){} People(int weight,double height):myweight(weight),myheight(height){} void calculatebmi() { mybmi= myweight / myheight * myheight; } void getAnswer(){ calculatebmi(); if (mybmi > 23.9)cout << "Yes!" << endl; else cout << "No！" << endl; } }; int main() { People a = People(); int weight; double height; cin >> weight >> height; a = People(weight, height); a.getAnswer; cin >> weight >> height; return 0; }

#include "stdafx.h" #include <iostream> using namespace std; class People { private:int myweight; double myheight; double mybmi; public: People() :myweight(0), myheight(0.0), mybmi(0.0){} People(int weight,double height):myweight(weight),myheight(height){} void calculatebmi() { mybmi= myweight / myheight * myheight; } void getAnswer(){ calculatebmi(); if (mybmi > 23.9)cout << "Yes!" << endl; else cout << "No！" << endl; } }; int main() { People a = People(); int weight; double height; cin >> weight >> height; a = People(weight, height); a.getAnswer(); return 0; } 是这个

[paschen]

a.getAnswer; 改成： a.getAnswer();

按照版主的办法，问题解决了么？ 这么简单的类，函数能少点不？函数定义和函数声明按照格式来吧，这代码看着好别扭。

多了个返回0吧？？。。。

#5 代码测试正常

这种问题就不要问了

[跑马溜溜的山上]

额！没有（），我以前也这样干过

VS2015运行没问题
