I'm having difficulty understanding why the following gives an infinite loop
on djgpp 3.0.2 but not on prev. versions nor on TC++ 3.0:
#include <iostream>
#include <fstream>
#include <cstdlib>
using namespace std;
int get_key();//problematic function
int main() {
cout<<get_key()<<endl;
return EXIT_SUCCESS;
}
int get_key() {
ifstream input("con");
//of course "con" is non-standard, but it's still a "file", so there should
be no problem
return input.get();
//get() creates infinite loop (well, not inf. loop, but it waits until I
press EOF [Cntr+Z]).
//get() is supposed to return next char in the istream after '\n is pressed,
not return
//next key only after EOF has been pressed.
//What am I doing wrong?
