Xcode

[jzone3]

I recently switched to xcode from microsoft visual C++ so:
how do you clear the screen
how do you change the screen color
and how do you make a pause (before i used
#include <ctime>
and
clock_t now;
now = clock();
while( clock() < now+2000 ) {}

how do you clear the screen
how do you change the screen color
and how do you make a pause

You usually don't need to care about these things, but see http://www.cplusplus.com/forum/articles/7311/

[jzone3]

what do you mean by not caring?
Also, i found clearing system("clear");
and pauses system(1);
but not the screen color

You can pause using Sleep() on Windows, or sleep() on OS X or any other POSIX. The difference is the parameter in Windows is in milliseconds, rather than seconds on POSIX.

As for all the console stuff, see http://msdn.microsoft.com/en-us/library/ms682073(VS.85).aspx

thank you but im not using windows (and i think i ment sleep instead of system)

That's me getting is wrong again.

If you want to control a terminal, you might want to consider using a curses library.

[jzone3]

thank you
im sorry but i am not familiar with the curses library can you please briefly explain it

You may want to read the Wikipedia link first.

you can try and use VT100 escape sequences. may even work in DOS box.

if you look at my latest post here: http://www.cplusplus.com/forum/general/27198/

I am playing with io manipulators, though it's in progress.
not finished it yet. may be better ways to do it.
may be of use, no warranty.
so I can do stuff like this...

    cout << clear << blink << "hello\n";
    cout << reset;
    cout << fg_yellow << bg_blue;;
    cout << "oi oi";
    cout << moveto(10,10) << bg_yellow << fg_blue << blink << "ponce features";
    cout << up(2) << "help" << left(14) << "up two";

ok ill try it l8r because it sounds complex and i am a begginer

[bigearsbilly]

not really, once you get the hang.
you on a mac?
if you open a command line terminal you can play with it,

"\033" is the ESCAPE character in octal

for example

printf "\033[5m"  # turn blink on
printf "\033[0m" # clear all attributes

See why you shouldn't care about TUI?

[jzone3]

ya when I do that should I take out the # turn blink on
