Structure of the Problem Requirements
Structure are use to organize and define your own data type in C++. Structure are just like class in C++ but class is more organize and safe as compare to structure . The main difference between class and structure is in their Encapsulation of data . Here is a very simple example of structure which define its way of defining and putting data in it .
Source Code
//Using a Box Structure
#include <iostream>
using namespace std;
//Structure to Represent a Box
struct Box
{
double length;
double height;
double breadth;
};
//Prototype of function to calculate the volume of a box
double volume (const Box& aBox);
int main()
{
cout<<"\n\n\n **************** STRUCTURE IN C++ ******************\n\n\n";
Box firstBox = {40.0, 30.0, 10.0};
//Calculate the volume of the box
double firstBoxVolume = volume(firstBox);
cout<<endl
<<"Size of first Box object is : \n"
<<firstBox.length
<<firstBox.breadth
<<firstBox.height
<<endl;
cout<<"Volume of first Box Object is : \n"<<firstBoxVolume
<<endl;
Box secondBox = firstBox; //Create a secondBox object the same as firstBox
//Increase the dimensions of second Box object by 10
secondBox.length += 10;
secondBox.breadth += 10;
secondBox.height += 10;
cout<<endl
<<"Size of second Box object is : \n"
<<secondBox.length
<<secondBox.breadth
<<secondBox.height
<<endl;
cout<<"Volume of second Box Object is : \n"<<volume(secondBox)
<<endl;
return 0;
}
//Function to calculate the volume of a box
double volume(const Box& aBox)
{
return aBox.length * aBox.breadth * aBox.height;
}
