Function overloading in Object Oriented Programming.

-
Function Overloading is the concept of object oriented programming in which we use same function name with different use.
In function overloading we use different parameter to differentiate with each other and this is the concept of Polymorphism feature of Object Oriented Programming.

EXAMPLE:

#include <iostream>
using namespace std;

class geopmetry 
{
public:
int area(int sideLength)    //same function name
{
return (sideLength*sideLength);
}
int area(int sideLength,int sideWidth) //same function name
{

return (sideLength*sideWidth);
}
int area(double sideLength)  //same function name
{
return (sideLength*sideLength*sideLength);
}
};
int main()
{
geopmetry geopmetryObj;
cout<<"area of square having length(10) ="<<geopmetryObj.area(10)<<"\n";
cout<<"area of rectangle having length(10),width(20) ="<<geopmetryObj.area(10,20)   <<"\n";
cout<<"volume of qube having length(10) ="<<geopmetryObj.area(10.0);
return 0;
}

Introduction to Python.

What is python? Python is an object-oriented programming language created by Guido Rossum in 1998. If you just beginning your programming career, python suits you best. With python you can do everything from GUI developement, web application, Machine learning, IOT, Game Developement etc. so it is general purpose high level programming language. It is very easy language,it is good for beginners. It is case sensitive language. Python is Dynamically Typed, Write less code do more. Introduction Easy to Learn and Use Python is easy to use and learn, it is user friendly and high level programming language. Expressive language Pyton language is more expressive means that is more understand and readable. Unique style Python is an interpreted language i.e interpreter execute the code line by line at a time . This makes debugging easy and thus suitable for beginners. Cross Platform Language Python can run equally on different platform such as windows, Linu...

Conditional Statement Decision making of an anticipation of condition occuring by execution of program and dpecific action is taken according to condtion. Following is a general form of typical decision making structure found in most programming language. Python programming language uses any non-zero or non-null value as true and if it is either zero or null then it is assume false value. if Condition: In python the block of statement is executed if the condition is true. Syntax if (condition): Block(s) Example var1=100 if var1: print('i got an true value') print(var1) output i got an true value 100 Question: Write a program that prompt user to enter two integer values, print the message "equal" if both entered value are equal a=int(input("Enter first number")) b=int(input("Enter second number")) if a==b: print("equal") output Enter fir...
