public:
inline float multi(float a,float b)
{
return(a*b);
}
inline float cube(float a)

float a1,b1;
clrscr();
cout<<"\n Enter Two Value ";
cin>>a1>>b1;
cout<<" Multiplication is :"<<obj.multi(a1,b1)<<endl;
cout<<" Cube of val1 is :"<<obj.cube(a1)<<endl;
cout<<" Cube of val2 is :"<<obj.cube(b1)<<endl;
getch();
