Alright this is my code:

Code:

#include <iostream>
#include <windows.h>
#include <string>
#include <stdlib.h>
using namespace std;

//Voids for colors
void blue()
{
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_INTENSITY | FOREGROUND_BLUE);
}

void red()
{
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_INTENSITY | FOREGROUND_RED);
}

void green()
{
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_INTENSITY | FOREGROUND_GREEN);
}

void cyan()
{
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_INTENSITY | FOREGROUND_BLUE | FOREGROUND_GREEN);
}

void yellow()
{
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_INTENSITY | FOREGROUND_GREEN | FOREGROUND_RED);
}

void white()
{
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_INTENSITY | FOREGROUND_BLUE | FOREGROUND_RED | FOREGROUND_GREEN);
}
//end of voids for colors

int main()
{
blue();
cout << "This is blue!" << endl;
cout << "*****************";
white();
cout << "This is white!";
blue();
cout << "blue again!" << endl;
cout << "also blue!" << endl;
cin.sync();
cin.ignore();
return 0;
}

What I want is this, the color part

Code:

SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_INTENSITY | FOREGROUND_BLUE | FOREGROUND_RED | FOREGROUND_GREEN)

Is there a way instead of writing all that to make it be just like this? The reason for asking is because making all those voids make it look "messy".

Code:

blue = GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_INTENSITY | FOREGROUND_BLUE | FOREGROUND_RED | FOREGROUND_GREEN

SetConsoleTextAttribute(Blue)

Thank you.

PS (I'm not sure if you will understand what I'm asking.)

Code:

private void setTextColor(string color)
{
Switch(color) {
case "blue":
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_INTENSITY | FOREGROUND_BLUE);
break;
case "red":
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_INTENSITY | FOREGROUND_RED);
break;
case "green":
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_INTENSITY | FOREGROUND_GREEN);
break;
case "cyan":
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_INTENSITY | FOREGROUND_BLUE | FOREGROUND_GREEN);
break;
case "yellow":
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_INTENSITY | FOREGROUND_GREEN | FOREGROUND_RED);
break;
case "white":
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_INTENSITY | FOREGROUND_BLUE | FOREGROUND_RED | FOREGROUND_GREEN);
break;

default:
color == "white";
break;
}

To assign a text color, simply write setTextColor("colorhere");

If your going to use

Code:

#define blue GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_INTENSITY | FOREGROUND_BLUE

SetConsoleTextAttribute(blue);

I suggest you to just use

Code:

#define blue() SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_INTENSITY | FOREGROUND_BLUE);

Since your going to define to every colour anyway.

Code:

void ChangeColor(int Color)
{
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), Color);
}

white = 15
red = 10 or 12
green = the other one that is not red

That is all I remember off the top of my head.

Just curious but do I need to add the () after blue or can I just leave it as

Code:

#define blue

You need the parentheses, you are defining a function, all functions have the parentheses whether empty or with parameters.

What? He doesn't need the parenthesis. He is not defining a function, if he were to use parenthesis it would be a macro. He has no need for that since he is not passing a variable to the macro. _________________ Mutilated lips give a kiss on the wrist of the worm-like tips of tentacles expanding in my mind I'm fine accepting only fresh brine you can get another drop of this yeah you wish

No need to call GetStdHandle EVERY time.

What exactly does GetStdHandle do? I just copied the code from somewhere and understood "most" of it except for that.
