Does anyone know what the equivilent of WIndows <graphics.h> for C++ avility to colors, etc. I have no Idea what it would be in Linux, can someone help me? Thanks.

I don't know graphics.h, so can you be a bit more
specific about what it provides? "Colours" is a bit
vague ...

Are you refering to the graphics library of Borland C++? In that case, the closest thing in Linux is probably the SDL library. See http://www.libsdl.org/index.php

This was done in windows I want to do it in Linux:
// Turbo C++ program

#include <iostream.h>
#include <graphics.h>
#include <math.h>

class RecursiveCurve {
public:
RecursiveCurve();
void readInitValues();
void snowflake();
void cross();
private:
double side, angle;
int level;
void right(double x) {
angle += x;
}
void left (double x) {
angle -= x;
}
void drawFourLines(double side, int level);
void drawCrossSide(double side, int level);
};

void RecursiveCurve::RecursiveCurve() {
setcolor(WHITE);
setbkcolor(BLUE);
moveto (200,150);
angle = 0.0;
cout << "Enter side and level: ";
cin >> side >> level;
}

void RecursiveCurve::drawFourLines(double side, int level) { // arguments to sin()
if (level == 0) // and cos() are angles
linerel((cos(angle*M_PI/180)*side), // specified in radians,
(sin(angle*M_PI/180)*side)); // i.e., the coefficient
else { // M_PI/180 is necessary;
drawFourLines(side/3.0,level-1);
left (60);
drawFourLines(side/3.0,level-1);
right(120);
drawFourLines(side/3.0,level-1);
left (60);
drawFourLines(side/3.0,level-1);
}
}

void RecursiveCurve::snowflake() {
for (int i = 1; i <= 3; i++) {
drawFourLines(side,level);
right(120);
}
}

void main() {
int grBoard = DETECT, grMode, grResult, grError;
initgraph(&grBoard,&grMode,"c:\\tc\\bgi");
grError = graphresult();
if (grError != grOk) {
cerr << "error: " << grapherrormsg(grError) << endl;
return;
}
RecursiveCurve().snowflake();
}

The SDL library would be a good choice for that.
