Continuous keyboard input in C

Question

I am creating a console application in C. This is a game in which characters are falling down and user has to press that specific key on the keyboard. I don\'t know how to detec

I think this might be the non-blocking keyboard input you are looking for.

void simple_keyboard_input()  //win32 & conio.h
    {
        if (kbhit())
          {
                KB_code = getch();
                //cout<<"KB_code = "<

And as for the characters falling down.. here you go.

Code for if you are on Windows:

/* The Matrix  falling numbers */

#include 
#include  

#include 
#include 
#include 
#include 
using namespace std;


#define KB_UP 72
#define KB_DOWN 80
#define KB_LEFT 75
#define KB_RIGHT 77
#define KB_ESCAPE 27
#define KB_F8 66


/* Variables*/

char screen_buffer[2000]={' '};
int y_coord[2000]={0};
int x=0, y=0,dy=0;
int XMAX=77;
int YMAX=23;
int KB_code=0;
bool QuitGame=false;
int platformX=35, platformY=23;

/* function prototypes*/

void gotoxy(int x, int y);
void clrscr(void);
void setcolor(WORD color); 
void simple_keyboard_input();  
void draw_falling_numbers();
void draw_platform();

/*  main  */

int main(void)
{
  /* generate random seed */
  srand ( time(NULL) );

  /* generate random number*/
  for(int i=0;iYMAX) y_coord[x]=0;

        /* draw dark color */
        setcolor(2);
        gotoxy(x ,y_coord[x]-1); cout<<"  "<74) platformX=74;
                break;

                case KB_UP:
                           //Do something                     
                break;

                case KB_DOWN:
                           //Do something                     
                break;

            }        

      }

}


void setcolor(WORD color)
{
    SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),color);
    return;
}


void gotoxy(int x, int y)
{
  static HANDLE hStdout = NULL;
  COORD coord;

  coord.X = x;
  coord.Y = y;

  if(!hStdout)
  {
    hStdout = GetStdHandle(STD_OUTPUT_HANDLE);
  }

  SetConsoleCursorPosition(hStdout,coord);
}


void clrscr(void)
{
  static HANDLE hStdout = NULL;      
  static CONSOLE_SCREEN_BUFFER_INFO csbi;
  const COORD startCoords = {0,0};   
  DWORD dummy;

  if(!hStdout)               
  {
    hStdout = GetStdHandle(STD_OUTPUT_HANDLE);
    GetConsoleScreenBufferInfo(hStdout,&csbi);
  }

  FillConsoleOutputCharacter(hStdout,
                             ' ',
                             csbi.dwSize.X * csbi.dwSize.Y,
                             startCoords,
                             &dummy);    
  gotoxy(0,0);
