i have a function that clear the screen and then display array to cout.
i compiled no error no warning, i run it, the screen really get "clear" but it does not display anything to cout, and it "clear screen" to blanks for 2 seconds, the screen return to this : ![](/images/imgserve.php?url=http://i19.photobucket.com/albums/b171/NickyEng/clear.jpg)
Here is my coding: -
/* screen.h */
-
#ifndef _SCREEN_H_
-
#define _SCREEN_H_
-
#include <string>
-
#include <iostream>
-
#include <fstream>
-
#include <cstdlib>
-
-
#include "array2d.h"
-
-
namespace Game{
-
using namespace std;
-
class Screen{
-
public:
-
Screen(): Xsize(80) , Ysize (23), myArray (Xsize,Ysize){};
-
-
~Screen(){}
-
-
/* clear the previous screen and display new screen image with Xsize Ysize */
-
void Paint(){
-
-
/* clear the screen */
-
system("clear");
-
-
// and then display the screen with width and height
-
-
for(unsigned y = 0; y < Ysize; y++){
-
for(unsigned x = 0; x < Xsize; x++){
-
cout << myArray.Get(Xsize , Ysize);
-
}
-
}
-
}
-
-
private:
-
unsigned Xsize;
-
unsigned Ysize;
-
Array2D<char> myArray;
-
string status;
-
-
-
/* testgame.cpp */
-
#include <iostream>
-
#include <string>
-
#include "screen.h"
-
#include "array2d.h"
-
-
using namespace std;
-
using namespace Game;
-
-
int main(){
-
Screen s;
-
s.Paint();
-
-
cout << "Testing screen display..." << endl;
-
-
return 0;
-
}
-
I insist want to use system("clear") , but i guess the problem is within the function Paint() where after system("clear") , it cannot continue to execute.
What's the problem?
Please help.
thanks.

This may nopt be the source of ur prob but methinks:
cout << myArray.Get(Xsi ze , Ysize);
should be
cout << myArray.Get(x , y);
firstly Xsize & Ysize are probably outside the bounds of the array (because the indexing starts at 0, and secondly I assume you are trying to loop through all the elemnts in the array

I am just trying to learn python, to use for some fairly basic command
line utilities which will run in either Windows/DOS or Linux. I cannot
find a platform neutral way of manipulating the screen. I don't want
to do anything complex, but just:-
1. Clear the screen
2. Print a string at an arbitrary x,y position
3. Receive a single key stroke
It seems that under Linux the curses module will do all this and more

Sorry one of those "C" type transistion questions which I
could find no answer for in existing C# text books.
In C, I used to use the system function call to execute
programs synchronously.
To clear the screen, for console based programs, I used
to include the following statement in my program.
system("cls"); // For DOS/windows based programs

i have a python program which attempts to call 'cls' but fails:
sh: line 1: cls: command not found
i tried creating an alias from cls to clear in .profile, .cshrc, and
/etc/profile, but none of these options seem to work.
my conclusion is that a python program that is executing does not use
the shell (because it does not recognize shell aliases). is this
correct?

Hi Guys,
Am using Windows 2000 and Dev C++ to create C programs. I'm trying to use clear screen and other graphic functions such as positioning output on screen. Have seen some documents that suggest i use curses.h or system("clear") for clear screen, for example but all this has failed.

Does anyone know how to clear the shell screen completely ? I tried
import os and then os.system("clear") was said to have worked in Windows
XP, but it's just bringing up another window, then it turns black and
then it closes in within about a second moving the prompt at the
os.system("clear") line . I've also tried os.system("cls") with the
same results.
thx

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
