This blog demonstrates how to calculate the volume of a cylinder using C++ programming language, including class definition, constructor usage, and method implementation.

#include<iostream>  
using namespace std;  
class cylinder{  
 public:  
 cylinder(double a,double b);  
 void vol();  
 private:
double r;
double h;  
double volume;  
};  
cylinder::cylinder(double a,double b)  
{  
    r=a;  
    h=b;  
    volume=3.1415*r*r*h;  
}  
void cylinder::vol()  
{  
    cout<<"The volume  is ："<<volume<<endl;  
}  
int main()  
{  
cylinder x(1.0,1.0);  
        x.vol();  
system("pause");  
 return 0;  
}
