What is the definition of 'getch' in c programming?

Answer 1

what is getch()and their use

Function getch waits for a single keypress (without line-buffering and echoing).

In: ncruses.h (unix) or conio.h (dos).

Answer 2

It has no use in C++ -- it is a hangover from C contained in the non-standard header, conio.h. Its purpose is to retrieve a character from the console without echoing to stdout (std::cout in C++). It was typically used in "Press any key to continue" applications in C (but not C++) but since the input is unbuffered, the onus is upon the programmer to handle buffering.

The following is an example in C (invalid for C++):

#include

#include

void main()

{

printf("Press any key\n");

getch();

}

The following is the C++ equivalent:

#include

int main()

{

std::cout<<"Press any key"<

std::getchar();

}

Answer 3

getch() is for waiting the o/p screen til we enter the inputs

Answer 4

GET CHaracter (with Echo). See the Help for details.
