cprintf Example

#include <conio.h>

int main(void)
{
   /* clear the screen */
   clrscr();

   /* create a text window */
   window(10, 10, 80, 25);

   /* output some text in the window */
   cprintf("Hello world\r\n");

   /* wait for a key */
   getch();
   return 0;
}

Putch Example

#include <stdio.h>
#include <conio.h>

int main(void)
{
   char ch = 0;

   printf("Input a string:");
   while ((ch != '\r'))
   {
      ch = getch();
      putch(ch);
   }
   return 0;
}

Getch Example

#include <conio.h>
#include <stdio.h>

int main(void)
{
  int c;
  int extended = 0;
  c = getch();
  if (!c)
    extended = getch();
  if (extended)
    printf("The character is extended\n");
  else
    printf("The character isn't extended\n");

  return 0;
}

Getche Example

#include <stdio.h>
#include <conio.h>

int main(void)
{
   char ch;

   printf("Input a character:");
   ch = getche();
   printf("\nYou input a '%c'\n", ch);
   return 0;
}
