INLINE FUNCTION IN C++

Stream is a sequence of bytes that serves as an input or output source. The input stream provides data to a program while the output stream receives output. The get() and put() functions handle single character I/O. The >> operator is overloaded in istream while << is overloaded in ostream. The ios class contains functions like width(), precision(), and fill() for formatting output. Iomanip provides manipulators to format output in a chained manner.

Classes allow users to bundle data and functions together. A class defines data members and member functions. Data members store data within each object, while member functions implement behaviors. Classes support access specifiers like public and private to control access to members. Objects are instances of classes that allocate memory for data members. Member functions can access object data members and are called on objects using dot notation. Friend functions allow non-member functions to access private members of classes.

This presentation describes runtime polymorphism (virtual functions) in C++, difference between method overloading & method overriding.

Pointer is a variable that stores the memory address of another variable. It allows dynamic memory allocation and access of memory locations. There are three ways to pass arguments to functions in C++ - pass by value, pass by reference, and pass by pointer. Pass by value copies the value, pass by reference copies the address, and pass by pointer passes the address of the argument. Pointers can also point to arrays or strings to access elements. Arrays of pointers can store multiple strings. References are alternative names for existing variables and any changes made using the reference affect the original variable. Functions can return pointers or references.

The document discusses inheritance in C++. It defines inheritance as deriving a class from another class, allowing code reuse and fast development. There are different types of inheritance in C++: single inheritance where a class inherits from one base class; multiple inheritance where a class inherits from more than one base class; multilevel inheritance where a derived class inherits from another derived class; hierarchical inheritance where multiple subclasses inherit from a single base class; and hybrid inheritance which combines different inheritance types. Examples of each inheritance type are provided in C++ code snippets.

This document discusses functions in C++. It defines what a function is and explains that functions are the building blocks of C++ programs. Functions allow code to be reused, making programs easier to code, modify and maintain. The document covers function definitions, declarations, calls, parameters, return types, scope, and overloading. It also discusses local and global variables as well as pass by value and pass by reference.

Command-line arguments are given after the name of the program in command-line shell of Operating Systems. To pass command line arguments, we typically define main() with two arguments : first argument is the number of command line arguments and second is list of command-line arguments.

Functions allow programmers to structure C++ programs into modular segments of code to perform individual tasks. There are two types of functions: library functions and user-defined functions. User-defined functions are defined using a return type, function name, and parameters. Functions can be called by value or by reference and can also be inline, recursive, or friend functions.
