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.
