Given the following class definition:

#includeiostream>

using namespace std;

class Color

{

private:

int red, green, blue;

int checkAndTruncate(int x);

public:

Color() { red = 0; green = 0; blue = 0; }

Color(int x) { red = green = blue = x; }

void read(istream &in) { in >> red >> green >> blue; }

void print(ostream &out) { out "[" red ","green "," blue "]"; }

void setRed(int r) { red = checkAndTruncate(r); }

void setGreen(int g) { green = checkAndTruncate(g); };

void setBlue(int b) { blue = checkAndTruncate(b); }

int getRed() { return red; }

int getGreen() { return green; }

int getBlue() { return blue; }

};

int Color::checkAndTruncate(int x)

{

if (x >= 0 && x

return x;

else if (x

{

return 0;

}

else

{

return 255;

}

}

Add + (binary) ++ (pre-increment) and (unary) operators so that the following main will generate the following output:

You MUST develop the operators in 3 different ways; 1-Member functions, 2- Non-Member functions and 3- Friend functions. So you need to submit 3 different programs.

Note: you are not allowed to change anything in the main

int main()

{

Color col1;

Color col2;

cout "Please enter the first color (red green blue):";

col1.read(cin);

cout "Please enter the second color (red green blue):";

col2.read(cin);

Color col3 = col1 + col2;

//printing the result of col1+col2 = col3;

col1.print(cout); cout " + "; col2.print(cout); cout " = "; col3.print(cout);cout endl;

// printing the result of col1++ = col4

col1.print(cout);

cout "++ =";

Color col4 = ++col1;

col4.print(cout); cout endl;

Color col5 = -col1;

//printing the result of -col1 = col5

cout "-"; col1.print(cout); cout " = "; col5.print(cout); cout endl;

return 0;

}

Note: The (unary) operator for colors is 255-color component for all components (red, green and blue).
