Here are various resources that are good to know about while learning the Go programming language. I created a list of commonly used Go packages and other dev tools at Go dev tools. getting started if you’re new to programming, check out Golang Tutorial For Beginners - YouTube A Tour of Go is probably the best way for developers with experience in another language to start learning Go Go Playground is an online Go editor and runner Tutorial: Get started with Go Go by Example Organizing a Go module Go FAQs go....

Ever wanted to move the cursor up while printing output in a program? You can. Here’s how with C++, and the same string works with any language in many terminals: cout << "\x1b[A"; That moves the cursor up one line. You can move it up by as many lines as you want; here’s how to move it up by 3 lines: cout << "\x1b[3A"; A variable works there too: int lines = 3; cout << "\x1b[" << lines << "A"; You can also move the cursor down, right, and left....

Every programmer should be comfortable with recursion. Recursion is a type of loop created by making a function call itself. Here’s a recursive function that loops infinitely (until the computer runs out of memory) when called: void print_stars() { cout << "*"; print_stars(); } Just like for loops and while loops, recursion can be used to do something repeatedly. Some problems are easier to solve with one kind of loop than another....

Printing emoji can be tricky because C++ running in Windows doesn’t always support UTF-8. Emoji and other Unicode symbols can be printed with C++ by copying the symbol itself into your code or by using a Unicode code point. You can find emoji and other symbols at sites like unicode-table.com or with a keyboard shortcut (Windows+. on Windows, ctrl+cmd+space on Mac, and ctrl+. on some Linux distros). On Mac and Linux, working with emoji in C++ is straightforward and doesn’t require any tricks....

You don’t need another dependency to color text. With many programming languages, you can change the color and the style of your output to a terminal using ANSI codes. Here’s how: with C++: cout << "\x1b[31m This will be red! \x1b[0m This will be the default color."; with Python: print("\x1b[31m This will be red! \x1b[0m This will be the default color.") As you can see, the string did not need to change at all even with a different programming language....

SQL (Structured Query Language) is a commonly used and reliable way for programs to store and retrieve data. In many cases, it’s much better in many ways than just using files directly. There’s a lot that can be learned about SQL. Here are some resources to get you started. Learn SQL with SQLBolt and/or The SQL Murder Mystery. Choose a database technology and tools. Databases by Full Stack Python is a guide (not entirely for Python) with various resources about databases....

Here are some great resources for learning how to use Git and GitHub. There’s more here than any one person will need, so just learn what will be helpful to you in the very near future. Watch these short videos: Version control with Git and GitHub by freeCodeCamp. Check out Better Explained’s guides to version control and Git, or the Learn X in Y minutes guide to Git. Consider starting with a Git client with a graphical interface, such as GitHub Desktop, GitButler, or Sublime Merge....
