Re: [Dev-C++] A very singular problem in Cpp

Indeed, system('pause') is rather messy (plus it's not really portable)
I usually do a system('pause') as a quick fix in the early stages of setting
up a program, I guess I'll use cin.get() from now on :)

This would make the program so:

#include <iostream>
using namespace std;
int main()
{
  //say hello :)
  cout<<"Hello World!\n";

  //wait for user keypress
  int pressed = cin.get();

  //ignores an extra keypress
  cin.ignore();

  /*
    do some more things here
  */
}

But why should I ignore an extra character in the input, since the cin.get()
will eat the key the user pressed?
could it be a '\n' vs. '\r\n' issue ?
