DO IN C++ PROGRAM: Using classes, data, methods and constructors, write a C++ program that ask the user for: -lenght l -width w -height h Solution Answer : #include <iostream> using namespace std; class Shape { public: int lenght, width, height; //data members Shape() //constructor { lenght=0; width=0; height=0; } void input() { cout<<\"\ Enter Length : \"; cin>>lenght; cout<<\"\ Enter Width : \"; cin>>width; cout<<\"\ Enter Height : \"; cin>>height; } void output() { cout<<\"\ \ Length : \"<<lenght; cout<<\"\ Width : \"<<width; cout<<\"\ Height : \"<<height; } }; int main() { Shape obj; //object declaration obj.input(); //member function call obj.output(); return 0; } .

1. DO IN C++ PROGRAM:
Using classes, data, methods and constructors, write a C++ program that ask the user for:
-lenght l
-width w
-height h
Solution
Answer :
#include <iostream>
using namespace std;
class Shape
{
public:
int lenght, width, height; //data members
Shape() //constructor
{
lenght=0;
width=0;
height=0;
}
void input()
{
cout<<" Enter Length : ";
cin>>lenght;
cout<<" Enter Width : ";
cin>>width;
cout<<" Enter Height : ";
cin>>height;
}
void output()

2. {
cout<<" Length : "<<lenght;
cout<<" Width : "<<width;
cout<<" Height : "<<height;
}
};
int main()
{
Shape obj; //object declaration
obj.input(); //member function call
obj.output();
return 0;
}
