Area using Function Overloading


Write a C++ program to find Area of square,rectangle,circle and triangle using Function Overloading. Here’s a Simple C++ program to find Area using Function Overloading in C++ Programming Language.


What is Overloading in C++ ?


C++ allows you to specify more than one definition for a function name or an operator in the same scope, which is called function overloading and operator overloading respectively.


Function overloading : :

You can have multiple definitions for the same function name in the same scope. The definition of the function must differ from each other by the types and/or the number of arguments in the argument list. You can not overload function declarations that differ only by return type.


Operators overloading : :

You can redefine or overload most of the built-in operators available in C++. Thus a programmer can use operators with user-defined types as well.

Overloaded operators are functions with special names the keyword operator followed by the symbol for the operator being defined. Like any other function, an overloaded operator has a return type and a parameter list.


Below is the source code for C++ program to find Area using Function Overloading which is successfully compiled and run on Windows System to produce desired output as shown below :


SOURCE CODE : :


/* C++ program to find Area using Function Overloading  */

#include<iostream>
using namespace std;
int area(int);
int area(int,int);
float area(float);
float area(float,float);
int main()
{
        int s,l,b;
        float r,bs,ht;
        cout<<"Enter side of a square:";
        cin>>s;
        cout<<"Enter length and breadth of rectangle:";
        cin>>l>>b;
        cout<<"Enter radius of circle:";
        cin>>r;
        cout<<"Enter base and height of triangle:";
        cin>>bs>>ht;
        cout<<"Area of square is"<<area(s);
        cout<<"\nArea of rectangle is "<<area(l,b);
    cout<<"\nArea of circle is "<<area(r);
    cout<<"\nArea of triangle is "<<area(bs,ht);
}
int area(int s)
{
    return(s*s);
}
int area(int l,int b)
{
    return(l*b);
}
float area(float r)
{
    return(3.14*r*r);
}
float area(float bs,float ht)
{
   return((bs*ht)/2);
}

OUTPUT : :


/*  C++ program to find Area using Function Overloading  */

Enter side of a square:2
Enter length and breadth of rectangle:3 6
Enter radius of circle:3
Enter base and height of triangle:4 4

Area of square is4
Area of rectangle is 18
Area of circle is 28.26
Area of triangle is 8

Above is the source code and output for C++ program to find Area using Function Overloading which is successfully compiled and run on Windows System to produce desired output.

This program appears incomplete

Hrushikesh

Means It looks partial
