Volume of Box using Constructor


Write a C++ Program To calculate Volume of Box using Constructor. Here’s a Simple Program To calculate Volume of Box using Constructor in C++ Programming Language.


What is Class and Objects in C++?


  • Class is a user defined data type, which holds its own data members and member functions, which can be accessed and used by creating instance of that class.
  • The variables inside class definition are called as data members and the functions are called member functions.
  • Class is just a blue print, which declares and defines characteristics and behavior, namely data members and member functions respectively. And all objects of this class will share these characteristics and behavior.

  • Objects are instances of class, which holds the data variables declared in class and the member functions work on these class objects.
  • Each object has different data variables. Objects are initialized using special class functions called Constructors.

Below is the source code for C++ Program To calculate Volume of Box using Constructor which is successfully compiled and run on Windows System to produce desired output as shown below :


SOURCE CODE : :


/*  C++ Program To calculate Volume of Box using Constructor */

#include <iostream>
using namespace std;

class box
{
    double length,width,height;
    double volume;

    public:
        box(double a,double b,double c);
        void vol();
};

box::box(double a,double b,double c)
{
    length=a;
    width=b;
    height=c;
    volume=length*width*height;
}

void box::vol()
{
    cout<<"\nDimensions of Box are :: \n";
    cout<<"\nLength of Box :: "<<length<<"\n";
    cout<<"\nWidth of Box :: "<<width<<"\n";
    cout<<"\nHeight of Box :: "<<height<<"\n";
    cout<<"\nVolume of Box :: "<<volume<<"\n";
}


int main()
{
    box x(2.4,5.7,2.1),y(3.3,4.4,5.5);

    x.vol();
    y.vol();

    return 0;
}

OUTPUT : :


/*  C++ Program To calculate Volume of Box using Constructor */


Dimensions of Box are ::

Length of Box :: 2.4

Width of Box :: 5.7

Height of Box :: 2.1

Volume of Box :: 28.728

Dimensions of Box are ::

Length of Box :: 3.3

Width of Box :: 4.4

Height of Box :: 5.5

Volume of Box :: 79.86

Process returned 0

Above is the source code and output for C++ Program To calculate Volume of Box using Constructor which is successfully compiled and run on Windows System to produce desired output.
