The process of detecting keystrokes using C++ involves several steps:

  1. Include the necessary header files for input/output and keyboard input detection:
#include <iostream>
#include <conio.h>
using namespace std;
  1. Initialize a variable to hold the key input value:
char c;
  1. Use the _getch() function from the conio.h library to get the input value:
c = _getch();
  1. Handle the key input value in your program logic:
if (c == 'a') {
  // do something if 'a' key is pressed
}
  1. Repeat the above steps in a loop to keep detecting keystrokes until the program is terminated:
while (true) {
  c = _getch();
  if (c == 'q') {
    break; // exit loop if 'q' key is pressed
  }
  // handle other inputs
}

Note: The above method of detecting keystrokes works only on Windows platforms. For cross-platform solutions, other libraries such as SDL or GLFW may be used.
