A forward declaration is an identifier declaration (such as a class, function, or variable) to inform the compiler about its existence before it is defined. This allows you to use the identifier in situations w
InC++, the creation of a new instance of the class is called instantiation. Memory is allocated for that object and the class constructor runs. Programmers can instantiate objects on the heap with a new keyword or on the stack as a variable declaration. Whenever an object of that class is ...
Here's a fun project attempting to explain what exactly is happening under the hood for some counter-intuitive snippets and lesser-known features in Python.While some of the examples you see below may not be WTFs in the truest sense, but they'll reveal some of the interesting parts of ...
Test Case 2: a = -1, b = -3 This would test the “Negative” branch of the if-else condition. By running these test cases, we can ensure that both branches of the if-else condition in the code are tested, which is the goal of White Box Testing. Illustaration: Imagine this...
This section describes what is a cookie - a piece of information sent by a Web server to a browser. The server expects the browser to send all cookies back to the server.
Before a function can be used, it must be declared, and this declaration includes information like the function’s name, return type, and parameter types. Later in the program, with the actual code that does the task, the function is defined. Once defined, a function can be called from ...
Theclosureis a special type of anonymous function that references variables declared outside of the function itself. This concept is similar to access the global variables which are available before the declaration of the function. Consider the below example, ...
Then we discuss orchestration platforms that enable the declaration and provisioning of cloud resources in a manner similar to that of a computer program, effectively specifying a solution architecture and the steps required to replicate it. Finally, we examine one of these orchestration platforms up ...

SyntaxError: Raised when the parser encounters invalid Python syntax (e.g., missing parentheses, invalid function declaration). IndentationError: It occurs when code blocks are not properly indented in Python’s required format. TabError: Raised when mixing tabs and spaces incorrectly for indentation ...
