Different data types in C++ include int, float, double, char, bool, and more.

• Some examples of data types in C++ are int (for integers), float (for floating point numbers), double (for double precision floating point numbers), char (for characters), bool (for boolean values), and string (for text).

• Other data types include long (for long integers), short (for short integers), unsigned int (for non-negative integers), and long double (for extended precision floating point number...read more

Python lists are mutable, while tuples are immutable, affecting how they can be used in programs.

• Mutability: Lists can be modified (e.g., list.append(1)), while tuples cannot (e.g., tuple[0] = 1 raises an error).

• Syntax: Lists use square brackets (e.g., my_list = [1, 2, 3]), while tuples use parentheses (e.g., my_tuple = (1, 2, 3)).

• Performance: Tuples are generally faster than lists for iteration due to their immutability.

• Use Cases: Lists are used for collections of items that...read more

Call by value passes a copy of the variable's value, while call by reference passes the variable's memory address.

• Call by value: changes made to the parameter inside the function do not affect the original variable.

• Call by reference: changes made to the parameter inside the function affect the original variable.

• Example: Call by value - int x = 5; func(x); // x remains 5. Call by reference - int y = 10; func(&y); // y becomes 20.

The 4 pillars of OOP are Inheritance, Encapsulation, Abstraction, and Polymorphism.

• Inheritance: Allows a class to inherit properties and behavior from another class.

• Encapsulation: Bundling data and methods that operate on the data into a single unit.

• Abstraction: Hiding the complex implementation details and showing only the necessary features of an object.

• Polymorphism: Ability of an object to take on many forms or have multiple behaviors.
