Changing text color in C++

RAA_Kr1cH · 13-October-05, 04:56 PM

This is way ahead of where my C++ 1 class is, but its been driving me nuts trying to figure out how to change colors in the dos box. What our teacher showed us was

system("color 3")

which depending on what number, or combination to 2 numbers changes the text and background colors. Unfortunately this changes the color of everything. What I want is a rediculously simple code that would allow me to change the text color of individual characters or lines of text. For example if I could do something like

cout << (RED) << "\nHello World!";

where it would change the color for just that particular line of code.

Thx

My first thought would be to use ANSI escape sequences:

So your code might look like:

cout << "\033[31;43mHello world\n"; // red on yellow

There are other ways too, using conio.h:

EDIT: I seem to recall the "\033[" was the escape sequence on Unix; I think in DOS it's ASCII character 27.
