Thread: continuous input?

I am looking to make a program that allows for individual keys to be used as a running tally (like the 'K' key is the integer '5') that continuously adds each integer, like if you press k, then immediately press k again, it will display 10. However, having almost no coding background, I would like to know if this is possible, and if so, how?

Not easily, and not with standard C.

You'll need to use libraries.

what about C++?

Same.

Use a library. For Linux, ncurses, I guess, for Windows, Win32. Or write a library that provides a common interface for both, but uses the two systems respective libs.

what about a way to just bypass enter. Like a do while loop. Like in this program

Code:

#include <iostream>

using namespace std;

int main()
{
  int a,b,
  cout<<"Please pick a number: ";
  cin>> a;
  cin.ignore();
  cout<<"you chose "<< a <<" your total is "<< a;
  cin.ignore();
  cout<<"Please pick another number: ";
  cin>> b;
  cin.ignore();
  cout<<"you chose "<< b <<" your total is "<< a + b;
  cin.ignore();

but put something in there for a, that if a is not return, run this part again

Code:

  int a,b,
  cout<<"Please pick a number: ";
  cin>> a;
  cin.ignore();
  cout<<"you chose "<< a <<" your total is "<< a;
  cin.ignore();

and when it is enter, end the program.

Code:

cin >> a;

won't return until you press enter.

what can I replace cin with though?

Not without pressing the enter key each time. Like User Name: said, use ncurses for Linux and Win32 for Windows.

ncurses are the same of pdcurses or are different versions of libraries doing similar things?
