console

问题 I'd believed that all global variables were accessible from the global object. So if I can access x (and x isn't bound locally), then window.x is the same value. However, in a webpage (on JSFiddle): window === this // true in Chrome and Firefox toString === window.toString // true in Chrome and Firefox But in the console: window === this // true in Chrome console and Firebug, false in Firefox web console toString === window.toString // false in Chrome, Firebug and Firefox web console Why is

问题 I noticed that any call to System.out.println() from a JAR file that hasn't been started by the command line (i.e. a Runnable JAR file started by user with double-click) won't open the console. After doing some research, I found multiple answers on the site: System.out.println in jar There is no problem doing like that. But where do you expect to see the output? What happens to “System.out.println()” in executable jar? If you run the code in some way that doesn't attach a console - such as

问题 The current selection of 16 colors from Console Colors is not the right choice for me. I would like to use much darker variants of these for the background. I could definitely set these using the UI and changing the RGB value there. For example, I could choose Darkblue and select 65 for Blue in the RGB section(128 is the default). Could some one tell me how to do this programmatically. Something like: (Get-Host).UI.RawUI.BackgroundColor=DarkBlue But with additional options. 回答1: This old post

问题 I have a small console based application that will solve physics equations. I am trying to ask the user if they want to find the ΔV in a given situation, but I can't figure out how to print the letter delta to the console. Here's my code: cout << "Select what you would like to find:\n" << "1 - Acceleration" << endl << "2 - Initial Velocity" << endl << "3 - Final Velocity" << endl << "4 - ΔV" << "\n\n"; cin >> choice; This does not print "ΔV" to the console. The "Δ" doesn't even display in my

问题 (C#) I am working on a program that is similar to RedBox which will have customer and manager functions.

Any help is appreciated as I am still somewhat new so any tips are appreciated,

问题 This question already has answers here : Why does my string not match when reading user input from stdin? (3 answers) Closed 1 year ago . I am currently working on a simple "user input" program. The user can enter a number, which I get with std::io::stdin().read_line(&mut let_name_here).ok().expect("Error"); . After getting the user input I want to print it to the console for a review. I have noticed strange behavior within the println! macro. The following code println!("Your input: {}", let
