function RGB()

Hello, i want to program text that comes on the screen in any desired color defined by a function, with given red, green and blue color values. I made a "Hello world" console application. Question: how can I make that function to steer the color of text. C language seemed to have had a function RGB(r,g,b) but it is strange to my MSC++ 6.0 compiler. I made some code but it doesn't work properly.

The code below gives errors:

--------------------Configuration: amber text - Win32 Debug-------------------- Compiling... amber text.cpp E:\msvc\MSDev98\MyProjects\amber text\amber text.cpp(377) : error C2512: 'Color' : no appropriate default constructor available E:\msvc\MSDev98\MyProjects\amber text\amber text.cpp(390) : fatal error C1070: mismatched #if/#endif pair in file 'E:\msvc\MSDev98\MyProjects\amber text\amber text.cpp' Error executing cl.exe.

amber text.exe - 2 error(s), 0 warning(s)

It doesn't recognize the class Color.

// amber text.cpp : Defines the entry point for the console application. //

include "stdafx.h"

include "stdio.h"

include "windows.h"

include "iostream.h"

include "wingdi.h"

include <windows.h>

//#define RGB(r,g,b) ( ((DWORD)(BYTE)r)|((DWORD)((BYTE)g)<<8)|((DWORD)((BYTE)b)<<16) )

//#include "Color.h"

ifndef COLOR_H_

define COLOR_H_

//#include //#include //#include <windows.h>

class Color { public: Color(unsigned char red, unsigned char green, unsigned char blue); Color(COLORREF); Color(const std::string&); private: friend class DC; COLORREF color_; };

Color::Color(unsigned char red, unsigned char green, unsigned char blue) : color_ (RGB(red, green, blue)) { }

Color::Color(COLORREF cr) : color_(cr) {

}

Color::Color(const std::string& colorName) { // if (colorName == "Amber") { // color_=RGB( 0xFF, 0xBF, 0x00); // }

if (colorName == "Dark Yellow") { color_=RGB( 0x99, 0xCC, 0x32); } }

int main(){ int Counter = 0; Color Kleur;

// Kleur.Color(Amber); while (Counter++ <= 254){

// SetTextColor(255,191,0); //SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), Counter); //textcolor(15); //rgb(255,191,0); printf("Hello World!\n"); } return 0; }
