Question

我在C ++项目中遇到编译错误。在我朋友的电脑上，我没有任何错误，但在我的电脑上，我得到以下信息：

第129行 - "Function Definition does not declare parameters "

第137行 - "'seats' was not declared in this scope"

我在Windows 7上运行Code :: blocks 10.05。

这是我的代码（注释表示行号）：

#include <iostream>
#include "Seat.h"
using namespace std;



class Plane

public:
    int viewSeat(int sNum) {
        if (seats[sNum].isFree()) {
            return 0;
        } else {
            //cout << "Debug (Plane::viewSeat(sNum) called)";
            string seatMess = "";
            switch (seats[sNum].getState()) {
                case 1:
                    seatMess = " is reserved for ";
                    break;

                case 2:
                    seatMess = " has been checked in by ";
                    break;
            }
            cout << "(X) Seat ";
            cout << seats[sNum].getCode();
            cout << seatMess;
            cout << seats[sNum].getFName() << " " << seats[sNum].getLName() << "\n";

我认为你错过了=

 Seat seats[32] = { {"1A"}, {"1B"}, {"1C"}, {"1D"},..

c ++函数定义不声明参数
