Function Overloading in C++

oops recall, basic operations and nesting of member functions

  /*OOPS---> Classes and Objects C++--> initially called as C with classes by stroustroup Class--> extension of structures in C Structures had limitations     - members are public     - a function cannot be created inside structure     - no methods Classes --> Structures + more Classes --> can have methods and properties Classes --> can make few members as private and few as public Structues in c++ are typedef (mtlb typedef na lgakr bi structures ke varibales define kre to vo hojaenge) you can declare objects along with class declaration like this:     class Employee {           class definition           } krishna, shalini; harry.salary = 9 makes no sense if salary is private */ /************NESTING OF MEMBER FUNCTIONS******** */ #include <iostream> using namespace std ; // int main(){     //     binary b; //     b.read(); //   ...

OBJECT ORIENTED PROGRAMMING, classes public and private access modifiers (syntax)

/**************OBJECT ORIENTED PROGRAMMING (oops)************ */ /*why oops??? #c++ language was designed with the main intention of adding object oriented features to C language #as the size of program increases readability, maintaibility and bug free nature of the program decreases. #this was tha main problem with langage C #as a result the possiblity of not addressing the problem in an effective way increases #also, as data was almost neglected, data security was easily compromised #using classes solves this problem by modelling program as a real world scenario PROCEDURE ORIENTED PROGRAMMING (POP) (jo abi tak kr rahe the) #consists of writing a sequence of instructions for the computer to follow #main focus is one functions and not on the flow of data #functions can either use local or global data #data moves openly from function to function OBJECT ORIENTED PROGRAMMING #Works on the basis of CLASSES and OBJECTS #A class is a template to create objects #treats data as a critical elem...
