1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 |
#include<iostream> using namespace std; class a { protected: int n; public: int cube() { cout<<"enter the number :"<<endl; cin>>n; for(int i=0; i<n; i++) { cout<<" cube of "<<i<<" is "<<"="<<(i*i*i)<<endl; } } }; int main() { a obj; obj.cube(); } |
Output
enter the number : 3
cube of 0 is 0.
cube of 1 is 1.
cube of 2 is 8
