The location where we can find a variable and also access it if required is called the scope of a variable. Python Local variable: Local variables are those that are initialized within a function and are […]

The “for” Loop is generally used to iterate through the elements of various collection types such as List, Tuple, Set, and Dictionary. Developers use a “for” loop where they have both the conditions start and t […]

Pass means performing no operation or in other words, it is a placeholder in the compound statement, where there should be a blank left and nothing has to be written there.

Everything in Python is an object and all variables hold references to the objects. The reference values are according to the functions; as a result, you cannot change the value of the references. However, you can […]

‘#’ is used to comment on everything that comes after on the line.

Just like its name a void pointer is a pointer that is not associated with anything or with any data type. Nevertheless, a void pointer can hold the address value of any type and can be converted from one data type to another

Just like its name, things can change suddenly and unexpectantly; So it is used to inform the compiler that the value may change anytime. Also, the volatile keyword prevents the compiler from performing […]

The delete operator is used to delete/remove all the characteristics/properties from an object by deallocating its memory; furthermore, it returns true or false in the end. In simple terms, it destroys or […]

Pointers are the variables that are used to store the address location of another variable. Operations that are permitted to a pointer are: Increment/Decrement of a Pointer Addition and Subtraction of […]

Virtual inheritance is a technique that ensures only one copy of a base class’s member variables is inherited by grandchild-derived classes. Or in simple terms, virtual inheritance is used when we are dealing w […]

The capability or ability of a class to derive properties and characteristics from another class is known as inheritance. In simple terms, it is a system or technique of reusing and extending existing classes […]

When a variable is described as a reference it becomes an alias of the already existing variable. In simple terms, a referenced variable is another named variable of an existing variable keeping in mind that […]

Arguments that are passed to the main() function of the program in the command-line shell of the operating system are known as command-line arguments.

Volatile keyword is used to prevent the compiler from optimization because their values can’t be changed by code that is outside the scope of current code at any time. The System always reads the current value o […]

In C, enumerations (or enums) are user-defined data types. Enumerations allow integral constants to be named, which makes a program easier to read and maintain. For example, the days of the week can be defined as […]

The structure is a keyword that is used to create user-defined data types. The structure allows storing multiple types of data in a single unit. The structure members can only be accessed through the structure variable.
