下面是我做的一个名为TheSecondVeryBestClassEverMade
的类(我已经做过以前有史以来最好的类,所以这就是为什么!)做了一个构造函数,并在参数中做了一个字符串z。在此构造函数的主体中,我介绍了另一个函数(在C ++中是一个函数,在Java中是方法?),并将字符串名称设置为z。
此后,我从TheSecondVeryBestClassEverMade
中创建了一个对象,并在其参数中创建了一个字符串,内容为:“曼波5号是我的果酱!” (因为这是一首很棒的歌曲吧!!),但是现在这些令人毛骨悚然的东西不会在终端中打印出来。
我在这里做什么错了?
这是我的c ++代码:
#include <iostream>
#include <string>
using namespace std;
//Constructor is a function that gets called automatically when a object is made.
// No more explicitly calling of the function, does it automatically!
class TheSecondVeryBestClassEverMade{
public:
//Constructors never have a return type so nothing gets returned in the body.
// Constructor name == as the class name:
TheSecondVeryBestClassEverMade(string z){
//DONT print anything out in a constructor, only IDIOTS do that.
// Are you a idiot? No don't think so buddy!
//Normally its used to give variables a initial value. EXAMPLE TIME:
setTheSecondVeryBestName(z);
}
void setTheSecondVeryBestName(string bb){
name = bb;
}
string getTheSecondVeryBestName(){
return name;
}
private:
string name;
};
int main() {
TheSecondVeryBestClassEverMade bodyOder("Mambo Number 5 is my jam baby!");
return 0;
}
答案 0 :(得分:2)
您制作了if (!categoriesTree.parent)) {
categoriesTree.parent = {'name': '', 'children': []};
}
categoriesTree.parent['children'].push({'name': category.name, 'id': category.id});
,并在其构造函数中给了它一个字符串,然后您对其进行了正确设置...但是您没有任何实际可打印它的代码。添加类似
bodyOder
然后在建立void printName(){
std::cout << "Name: " << name << std::endl;
}
之后调用它:
bodyOder
