not waiting for keyboard input (overloaded input stream operator) in C++

Does that help A common issue with input stream, especially in visual c++, is that you need .ignore(). This will prevent the input from getting ignored. If I remember correctly, just do cin.ignore() right before (or is it after) the first cin. I think that should do it.

Get Input from keyboard without waiting for input

fixed the issue. Will look into that further You need a special CONSOLE INPUT/OUTPUT library like NCURSES or Borland's CONIO to do that. Can't do it with standard C library.
If you are using Windows exclusively, take a look at Windows Console Functions.

Overloaded input operator failing automated simple input test

hop of those help? So I'm failing a simple input test for one of assignment questions. I'm to parse two integers separated by a white space. The two integers are used in the private members num and denom of the Rationalnumber type I have defined as a class. Is there something obviously unconventional I am using in or missing from this code? This code works for all my tests. , This code passes the test!:
code :
std::istream &operator>>( std::istream &is, Rationalnumber &r ) {   
    Rationalnumber::in++;   // increment counter

    int in;
    is >> in;
    r.numerator(in);
    is >> in;
    r.denominator(in);

    return is;
}

Using JUnit to test a main method that requires simulation of keyboard input with an input stream?

Does that help Let's suppose I have a program with a main method that uses the java.util.Scanner class to receive user input. , You can redirect System.out, System.in, and System.err like this:
code :
System.setOut(new PrintStream(new FileOutputStream("output")));

System.setErr(new PrintStream(new FileOutputStream("error")));

System.setIn(new FileInputStream("input"));

Reading File with Strings using overloaded input stream operator>>

This might help you I'm trying to get inputs from a file by overloading the istream operator. For that, I declared it as friend of a class. Then, I take as input that same class like this: , This...
code :
while (!in.eof()) {
string name;
int age;
while (in >> name >> age)
    ...do stuff...
char dot;
string name;
int age;
while (in >> dot && dot == '.' && in >> name >> age)
    ...do stuff...

waiting for keyboard input

wish helps you The Android key system is event-based, it does not work like the old ask-and-wait mechanisms of C/C++ etc for obtaining user input.
If you blocked/waited - then what would happen if the user pressed the Home key (you can't catch that) or navigated to another app - your app would force close because it would still be waiting and your onPause etc would not execute.
