A bit late now, but here’s how to access keyboard state in a console application. Note that it’s not all managed code as it requires GetKeyState to be imported from User32.dll. /// <summary> /// Codes representing keyboard keys. /// </summary> /// <remarks> /// Key code documentation: /// http://msdn.microsoft.com/en-us/library/dd375731%28v=VS.85%29.aspx /// </remarks> internal enum KeyCode : int … Read more
Try java.io.Console.readPassword. You’ll have to be running at least Java 6 though. /** * Reads a password or passphrase from the console with echoing disabled * * @throws IOError * If an I/O error occurs. * * @return A character array containing the password or passphrase read * from the console, not including any line-termination … Read more
$output = preg_replace(‘/([.!?])\s*(\w)/e’, “strtoupper(‘\\1 \\2’)”, ucfirst(strtolower($input))); Since the modifier e is deprecated in PHP 5.5.0: $output = preg_replace_callback(‘/([.!?])\s*(\w)/’, function ($matches) { return strtoupper($matches[1] . ‘ ‘ . $matches[2]); }, ucfirst(strtolower($input)));
Your code would become: def Survey(): print(‘1) Blue’) print(‘2) Red’) print(‘3) Yellow’) while True: try: question = int(input(‘Out of these options\(1,2,3), which is your favourite?’)) break except: print(“That’s not a valid option!”) if question == 1: print(‘Nice!’) elif question == 2: print(‘Cool’) elif question == 3: print(‘Awesome!’) else: print(‘That\’s not an option!’) The way this … Read more
As Michael said, the issue is buffering. By default, output is buffered until you print a newline (or until the buffer is full if you have really long lines), so you’ll most often see this issue when trying to do same-line prompts using putStr like you’re doing. I suggest defining a small helper function like … Read more
The event when user releases his finger is MotionEvent.ACTION_UP. I’m not aware if there are any guidelines which prohibit using View.OnTouchListener instead of onClick(), most probably it depends of situation. Here’s a sample code: imageButton.setOnTouchListener(new OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { if(event.getAction() == MotionEvent.ACTION_UP){ // Do what you want return true; … Read more
Use scanf(“%d”,&rows) instead of scanf(“%s”,input) This allow you to get direcly the integer value from stdin without need to convert to int. If the user enter a string containing a non numeric characters then you have to clean your stdin before the next scanf(“%d”,&rows). your code could look like this: #include <stdio.h> #include <stdlib.h> int … Read more
Console.Write(“\b \b”); will delete the asterisk character from the screen, but you do not have any code within your else block that removes the previously entered character from your pass string variable. Here’s the relevant working code that should do what you require: var pass = string.Empty; ConsoleKey key; do { var keyInfo = Console.ReadKey(intercept: … Read more
Is it ever useful to use Python 2’s input over raw_input? No. input() evaluates the code the user gives it. It puts the full power of Python in the hands of the user. With generator expressions/list comprehensions, __import__, and the if/else operators, literally anything Python can do can be achieved with a single expression. Malicious … Read more
Use the raw_input() function to get input from users (2.x): print “Enter a file name:”, filename = raw_input() or just: filename = raw_input(‘Enter a file name: ‘) or if in Python 3.x: filename = input(‘Enter a file name: ‘)
