In C++, you have several options for working with arrays: 1. Static Arrays: These are fixed-size arrays where the size is known at compile time. You declare them like this: int myArray[5]; // Declares an integer array with a fixed size of 5 Th

strct vs class

C++
3 years ago
In object-oriented programming (OOP), both classes and structures are used as building blocks for creating objects and defining their properties and behavior. However, there are some differences between classes and structures in most programming l

std varient

C++

std::variant is a type-safe union in C++17 and later, which can hold an object of one of several types, but only one type at a time. The type of the contained object can be checked at runtime, and a specific type can be extracted from the variant.

Evaluation order

n C++17 and above, the evaluation order of function arguments is guaranteed to be left-to-right. This means that if a function is called with multiple arguments, the expressions for those arguments will be evaluated in the order they appear in t
