Linux Console Color (the "\033[" way)-蒲公英云

This is a list of codes used in C++ to change the text color:

black - 30
red - 31
green - 32
brown - 33
blue - 34
magenta - 35
cyan - 36
lightgray - 37

Now these are the basic colours.

Usage of “\033[“:
This is to handle the console cursor. I do not have a complete reference so I ask people who know about it to comment with what I do not have.

* ‘m’ character at the end of each of the following sentences is used as a stop character, where the system should stop and parse the \033[ sintax.
\033[0m - is the default color for the console
\033[0;#m - is the color of the text, where # is one of the codes mentioned above
\033[1m - makes text bold
\033[1;#m - makes colored text bold**
\033[2;#m - colors text according to # but a bit darker
\033[4;#m - colors text in # and underlines
\033[7;#m - colors the background according to #
\033[9;#m - colors text and strikes it
\033[A - moves cursor one line above (carfull: it does not erase the previously written line)
\033[B - moves cursor one line under
\033[C - moves cursor one spacing to the right
\033[D - moves cursor one spacing to the left
\033[E - don’t know yet
\033[F - don’t know yet

\033[2K - erases everything written on line before this.

**(this could be usefull for those who want more colors. The efect given by bold will give a color change effect)

As a short and simple example that colors text and the bold version:

1 #include <stdio.h>
 2 
 3 int main(int argc, char ** argv)
 4 {     
 5     printf("\033[0mHello world!........................................[");
 6     printf("\033[1;32mOK");
 7     printf("\033[0m]\n");
 8     
 9     return 0;
10 }
1 #include   <stdio.h> 
  2 #include   <stdlib.h> 
  3 #include   <string.h>
