错误:预期';'在 '{' 标记之前 - 原因是什么? [英] error: expected `;' before '{' token - What is the cause?

问题描述

这是我的实现文件:

using namespace std;

#include <iostream>
#include <iomanip>
#include <string>
#include <stack>  //line 5
#include "proj05.canvas.h"

//----------------Constructor----------------//

Canvas::Canvas() //line 10
{
  Title = "";
  Nrow = 0;
  Ncol = 0;
  image[][100];  // line 15
  position.r = 0;
  position.c = 0;
}

//-------------------Paint------------------// line 20
void Canvas::Paint(int R, int C, char Color) 
{
  cout << "Paint to be implemented" << endl;
}

我得到的错误是:

proj05.canvas.cpp: In function 'std::istream& operator>>(std::istream&, 
    Canvas&)':
proj05.canvas.cpp:11: error: expected `;' before '{' token
proj05.canvas.cpp:22: error: a function-definition is not 
    allowed here before '{' token
proj05.canvas.cpp:24: error: expected `}' at end of input
proj05.canvas.cpp:24: error: expected `}' at end of input

这些看起来像是简单的语法错误，但我不确定是什么问题.有人可以为我解码这些吗?我真的很感激，感谢您的时间！

These seem like simple syntax errors, but I am not sure what's wrong. Could someone decode these for me? I'd really appreciate it, thanks for your time!

编辑

这是我的 .h 文件中 Canvas 的定义:

Here is the definition of Canvas in my .h file:

#ifndef CANVAS_H 
#define CANVAS_H 

#include <iostream>
#include <iomanip>
#include <string> 
#include <stack> 

class Canvas
{
  public: 
      Canvas(); void Paint(int R, int C, char Color); 
       const int Nrow; 
       const int Ncol; 
       string Title; 
       int image[][100]; 
       stack<int> path; 
       struct PixelCoordinates 
       {  
         unsigned int r; 
         unsigned int c;
       } position; 
}; 

#endif 

推荐答案

"proj05.canvas.h" 我敢打赌问题就在那里.也许没有 ;课后定义

"proj05.canvas.h" i bet the problem is there. may be no ; after class def
