Simple syntax error still eluding me.
- by melee
Here is the header for a class I started:
#ifndef CANVAS_
#define CANVAS_
#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;
Canvas operator<< (const Canvas& One );
Canvas operator>>( Canvas& One );
};
/*-----------------------------------------------------------------------------
Name: operator<<
Purpose: Put a Canvas into an output stream
-----------------------------------------------------------------------------*/
ostream& operator<<( ostream& Out, const Canvas& One )
{
Out << One.Title << endl;
Out << "Rows: " << One.Nrow << " Columns: " << One.Ncol << endl;
int i,j;
for( i=0; i<One.Nrow; i++)
{
cout<<"\n\n\n";
cout<< " COLUMN\n";
cout<< " 1 2 3";
for(i=0;i<One.Nrow;i++)
{
cout<<"\nROW "<<i+1;
for(j=0;j<One.Ncol;j++) cout<< One.image[i][j];
}
}
return Out;
}
/*-----------------------------------------------------------------------------
Name: operator>>
Purpose: Get a Canvas from an input stream
-----------------------------------------------------------------------------*/
istream& operator>>( istream& In, Canvas& One )
{
// string Line;
// int Place = 0;
// {
// In >> Line;
// if (In.good())
// {
// One.image[Place][0] = Line;
// Place++;
// }
// return In;
#endif
Here is my implementation file for class Canvas:
using namespace std;
#include <iostream>
#include <iomanip>
#include <string>
#include <stack>
#include "proj05.canvas.h"
//----------------Constructor----------------//
Canvas::Canvas()
{
Title = "";
Nrow = 0;
Ncol = 0;
image[][100] = {};
position.r = 0;
position.c = 0;
}
//-------------------Paint------------------//
void Canvas::Paint(int R, int C, char Color)
{
cout << "Paint to be implemented" << endl;
}
And the errors I'm getting are these:
proj05.canvas.cpp: In function 'std::istream& operator>>(std::istream&, Canvas&)':
proj05.canvas.cpp:11: error: expected `;' before '{' token
proj05.canvas.cpp:24: error: expected `}' at end of input
From my limited experience, they look like simple syntax errors but for the life of me, I cannot see what I am missing. I know putting a ; at the end of Canvas::Canvas() is wrong but that seems to be what it expects. Could someone please clarify for me?
(Also, I know much of the code for the << and operator definitions look terrible, but unless that is the specific reason for the error please do not address it. This is a draft :) )
