C++ Tutorials - Absolute n00b spoonfeed

This is very simple example of matrix effect (lol). Tell me what do you think? I would like to see if somebody has done / can do this better?
As you can see this is not the most efficient peace of code I could not even get this work with a function.
It is possible to draw something there with white spaces " " and thats why i tried to remove those "bad characters" like . , ' - etc.
Dont get confused because of my comments. I am not sure if I commented it right.

It should compile fine with VC++ 2008 Express Edition.

Code: Select all

#include "stdafx.h"
#include <ctime>
#include <cstdlib>
#include <iostream>
#include <windows.h>
using namespace std;

int main()
{
   //green color for text
   system("color 0a");

   //random seed
   srand(time(0));

   char random_char = ((rand() % 127));
   bool going = true, checking = true;
   
   while (going = true)
   {
      //draw row of characters (38 characters)
      for (int x = 0; x < 38; x++)
      {
         //generate first char
         random_char = ((rand() % 127) + 50);
         checking = true;
         while (checking)
         {
            if  ( //check for:
               // Bad/Small characters.
                  (random_char == 32) || (random_char == 39) || (random_char == 46) ||
                  (random_char == 44) || (random_char == 34) || (random_char == 45) ||
                  (random_char == 58) || (random_char == 59) || (random_char == 94) ||
                  (random_char == 95) || (random_char == 96) || (random_char == 126)
               // If bad character is generated -> generate new random character and check if it is bad
                )
            random_char = ((rand() % 127) + 50);
            
            //Good character found -> Continue to print it
            else break;
         }
         //Print character + white space
         cout << random_char << " ";
      }
      //Full row of characters successfully printed -> continue for next row
      cout << endl;

      //Delay
      Sleep(20);
   }
   system("pause");
   return 0;
}

very very nice, Ill make a version of it

here I wrote this in about a minute nothing pretty but a little closer to the look

its on a infinite loop so either control break or just close to stop it

Code: Select all

#include <ctime>
   
    #include <iostream>
    #include <windows.h>
int main()
{
   system("color 0a");
   srand((unsigned)time(0));

   char text;
   
   while(1)
   {
      text = rand() + 255;

      if (text < 20 || text == 33 )
         std::cout<< " ";
      else
      std::cout<< (char)text;
      Sleep(1);
   }
}


what was this for?

Code: Select all

//#include <cstdlib>


Ok half hour later.

Code: Select all

#include "stdafx.h"
#include <ctime>
#include <cstdlib>
#include <iostream>
#include <windows.h>
using namespace std;


char d[256];
bool going = true;
int X=0, Y=0;
int CurrentChar=64;
void gotoxy ( short x, short y )
{
  COORD coord = {x, y};
  SetConsoleCursorPosition ( GetStdHandle ( STD_OUTPUT_HANDLE ), coord );
}






int main()
{   
   system("color 0a"); //green color for text
   
   for(int x=0;x<255;x++)d[x]=x;

 
   srand(time(0));  //random seed

     
   while (going = true)
   {
      // 64-94
      
       Y=0;
      X=(rand() % 80);
        for (; Y < 24; Y++)
        {
         CurrentChar=(rand() % 30+94);
         gotoxy(X,Y);
          cout<< d[CurrentChar];
          Sleep(10);
          gotoxy(X,Y);
          cout<<" ";       
   
       }         
       
   }
   system("pause");
   return 0;
}


Awesome! Nice job guys!

yours turned out better than mine glinka

I just came across something interesting with this program and that is I went back to my program I'm working on and when I went to run it and to my surprise all the text was still green.

I don't know if it is because its using the system call or because I have to break out of it so it doesn't close right

EDIT: what ever the hell happened it changed the properties in my command prompt properties now if I could figure out how that happen I would change other properties that I need that way

Using system isn't such a great idea for anything - use the method for color text i posted in the other thread.

Nice, but those variables should be locally declared not globally.

nice code guys..

Hey i just wanted to give u a reak nice style looking to your program and so decided to make a little nice cool icon and stick it up with ur program and they are so cool united well here it is it.

PS: i used LiquidIcon to draw icon, plus that program has feature to extract icons to , but the one i put in ur program i made it ehehee
