How to Open a Folder in VSC with CMD

-
Image
Visual Studio Code (VS Code) Environment Visual Studio Code (VS Code) has established itself as an indispensable code editor for developers worldwide due to its lightweight build, robust ecosystem of extensions, customizability, and deep terminal integration. When working on complex web applications, backend scripts, or data pipelines, efficiency is paramount. While many developers rely on the right-click context menu ( "Open with Code" ) in Windows File Explorer, this option is not always checked during installation or can frequently break after Windows system updates and reinstallations. Fortunately, you can bypass the Graphical User Interface (GUI) entirely and launch any project folder directly into VS Code via the Windows Command Prompt (CMD) or Windows PowerShell. This step-by-step guide covers multiple ways to open directories using terminal commands, advanced command-line arguments, and h...

Scenario Listen to this story: a boy and his father, a computer programmer, are playing with wooden blocks. They are building a pyramid. Their pyramid is a bit weird, as it is actually a pyramid-shaped wall - it's flat. The pyramid is stacked according to one simple principle:  👉 each lower layer contains one block more than the layer above 👈 . The figure illustrates the rule used by the builders: building blocks Your task is to write a program which reads the number of blocks the builders have, and outputs the height of the pyramid that can be built using these blocks.

Scenario A car's fuel consumption may be expressed in many different ways. For example, in Europe, it is shown as the amount of fuel consumed per 100 kilometers. In the USA, it is shown as the number of miles traveled by a car using one gallon of fuel. Your task is to write a pair of functions converting l/100km into mpg " mile per gallon ", and vice versa . Sandbox The functions: are named liters_100km_to_miles_gallon and miles_gallon_to_liters_100km respectively ; take one argument (the value corresponding to their names) Complete the code in the editor. Run your code and check whether your output is the same as ours. Here is some information to help you: 1 American mile = 1609.344 metres; 1 mile = "1.60934" meters 1 American gallon = 3.785411784 litres. Expected output 60.31143162393162 31.36194444444444 23....
