getch function in c++

The getch function in C++ is not a standard function in the C++ library. However, if you're referring to the getch function commonly used in the Microsoft C/C++ compiler's conio.h library, here's a brief explanation:

  1. Include the conio.h header file in your program using #include <conio.h>.

  2. Call the getch function to capture a single character input from the user. It does not require the user to press the Enter key.

Here is an example of how the getch function can be used:

#include <iostream>
#include <conio.h>

int main() {
    char ch;
    std::cout << "Press any key: ";
    ch = getch();
    std::cout << "You pressed: " << ch << std::endl;
    return 0;
