getche() function in C:

getche() function is a function in C programming language which waits for any character input from keyboard and it will also echo the input character on to the output screen. Please find below the description and syntax for above file handling function.

File operation	Declaration & Description
getche()	Declaration: int getche(void); This function waits for any character input from keyboard. And, it will also echo the input character on to the output screen.

Example program for getche() function in C programming language:

This is a simple Hello World! C program. After displaying Hello World! in output screen, this program waits for any character input from keyboard. After any single character is typed/pressed, this program returns 0. But, please note that, getche() function will wait for any keyboard input (and press ENTER) and it will display the given input character on output screen immediately after keyboard input is entered.

#include <stdio.h>
int main()
{
    char flag;
    /* Our first simple C basic program */
    printf("Hello World! ");
    printf("Do you want to continue Y or N");
    flag = getche(); // It waits for keyboard input.
    if (flag == 'Y')
    {
       printf("You have entered Yes");
    }
    else
    {
       printf("You have entered No");
    }
    return 0;
}

#include <stdio.h>

int main()

{

char flag;

/* Our first simple C basic program */

printf("Hello World! ");

printf("Do you want to continue Y or N");

flag = getche(); // It waits for keyboard input.

if (flag == 'Y')

{

printf("You have entered Yes");

}

else

{

printf("You have entered No");

}

return 0;

}

Output:

Hello World!
Do you want to continue Y or N
Y
You have entered Yes

Note:

To use getch(), getche() functions, you need to include #include <conio.h> header file which is a non-standard header file.
