Question

#include <iostream>

using namespace std;

char sell;
int crew;
char you [50];
int ships =1;
int money;
int choice;

class ship{
public:
void sell_shii(){
cout<<"Do you wish to seel your ship?"<<endl;
cout<<"1to sell ship and 2to cancel"<<endl;


cin>>sell;
if (sell==1 && ships >0){
cout<<"You sold your ship"<<endl;
ships+=sell;



}else{
cout<<"You didnt sell your ship"<<endl;
}
}
}





int main()
{



cout<<"What is your name captain?"<<endl;
cin>>you;
cout<<"Welcome captain "<<you<<endl;

cout<<"You have "<<ships<<"ship/s";

cout<<"What would you like to do?\n 1 buy ships 2 sell ships\n 3 battle\n
cin<<choice;

switch (choice)

case 1:
buyship()
break;
case 2:
sellshii()
break;
case 3;
battle();

return 0;

}

我的“{”其中int main似乎不起作用，我做了什么？

出现的错误是

C:\Users\Ethan\Desktop\New folder.IPA\C++\Ship game\main.cpp|37|error: new types may not be defined in a return type|
C:\Users\Ethan\Desktop\New folder.IPA\C++\Ship game\main.cpp|37|error: extraneous `int' ignored|
C:\Users\Ethan\Desktop\New folder.IPA\C++\Ship game\main.cpp|37|error: `main' must return `int'|
C:\Users\Ethan\Desktop\New folder.IPA\C++\Ship game\main.cpp|37|error: return type for `main' change to "int"

Answer 1

在您定义}之前，您需要在课程定义的最后添加分号（最终main。）

没有它，它认为你试图将类定义为main的返回类型的一部分，因为两者之间没有分隔符，因此错误消息：

error: new types may not be defined in a return type

当然，它也会抱怨，因为您还没有从int返回main类型（因为您已经将int丢弃了之后）在不知情的情况下，指定了一个返回类型）：

error: extraneous 'int' ignored
error: 'main' must return 'int'
error: return type for 'main' change to "int"

我的int main（）{}出了点问题
