getch(): getch() is a nonstandard function and is present in conio.h header file which is mostly used by MS-DOS compilers like Turbo C.&nbsp; it reads&nbsp; a single character from keyboard. But it does not use any buffer, so the entered character is immediately returned without waiting for the enter key. Syntax: int getch(); #include &lt;stdio.h&gt; #include &lt;conio.h&gt; int&nbsp;main() { printf(&quot;%c&quot;, getch()); return&nbsp;0; } Input: g (Without enter key) Output: Program terminates immediately. But when you use DOS shell in Turbo C, it shows a single g, i.e., &#39;g&#39; getche() Like getch(), this is also a non-standard function present in conio.h. It reads a single character from the keyboard and displays immediately on output screen without waiting for enter key. Syntax: int getche(void); #include &lt;stdio.h&gt; #include &lt;conio.h&gt; // Example for getche() in C int&nbsp;main() { printf(&quot;%c&quot;, getche()); return&nbsp;0; } Input: g(without enter key as it is not buffered) Output: Program terminates immediately. But when you use DOS shell in Turbo C, double g, i.e., &#39;gg&#39;

getch():

it reads a single character from keyboard. But it does not use any buffer, so the entered character is immediately returned without waiting for the enter key.
Syntax:
int getch();
#include <stdio.h>
#include <conio.h>
int main()
{
printf("%c", getch());
return 0;
}
Input: g (Without enter key)
Output: Program terminates immediately.
But when you use DOS shell in Turbo C,
it shows a single g, i.e., 'g'
getche()
Like getch(), this is also a non-standard function present in conio.h. It reads a single character from the keyboard and displays immediately on output screen without waiting for enter key.
Syntax:
int getche(void);
#include <stdio.h>
#include <conio.h>
// Example for getche() in C
int main()
{
printf("%c", getche());
return 0;
}
Input: g(without enter key as it is not buffered)
Output: Program terminates immediately.

double g, i.e., 'gg'
