Why do we write getch() in turbo c?

Answer 1

No need when you are using int main , replace it by return 0.

It is used under header file conio.h specially to make programm stable means it remains on output screen till you
Press any other key......

Answer 2

Basically its job to take one character from the keyboard

Answer 3

Its use for holding prompt screen until any character press by the person.

Answer 4

I would recommend to stop using turbo c++, it is not even updated for decades and it is non-standard !

getch() is a part of turbo c++, which is taught to us in schools. Now, I use codeblocks which has C++11/14 in it.

As an alternative to getch(), you have system("pause"), which is a function in cstdlib which you can include as,

#include <cstdlib>

Also you've used clrscr(), for that we've system("clear") in the same header file / library.

Answer 5

It is used in some c compilers like turbo c.
Used to hold the output screen and wait until user press any key.
So, the screen remains stable, hence we can able to see the output on the screen.

[Just try the code without getch(), your output screen will just blink & go, you can't see or analyze your output]

Answer 6

getch() is used in turbo c just to hold the screen to get the output to the user, which have a presence due to header file conio.h in library.

Answer 7

Getch() us a character input which is used to take a character from the user at run time

Answer 8

Well it does same thing like getchar() but the difference is getchar () echoes the character keyed on screen while getch() doesn't. And it is also used to hold the screen for output

Answer 9

getch() is used to hold the output screen.

Answer 10

Answer 11

getch() function mean
To get a character
So,
At end compiler want a character
He waiting for a character

When you press a key then he got that character
And he over the program

Answer 12

getch () function reads character from keyboard.

Answer 13

getch ()
always get a character from user to hold the screen

Answer 14

getch() is a way to get a user inputted character. It can be used to hold program execution, but the "holding" is simply a side-effect of its primary purpose, which is to wait until the user enters a character.

Answer 15

getch() function is used in some c compilers and turbo c to hold up the output screen (i.e the screen waits until any input is given or any key is pressed)so that we are able to read the characters in our output

Answer 16

By using this curser will remain on output screen until you press any key

Answer 17

To hold the screen i guess

Answer 18

For Holding screen

Answer 19

We have to write getch() in the code for hold the screen, and we get seen clearly our answers.

Answer 20

hold the screen & wait for single character from keyboard.
