#include<iostream> #include<math.h> using namespace std; class a { protected: int rem,T4Tutorials_Octal,count; }; class b:virtual public a { protected: int T4Tutorials_Octal; }; class c:public b { public: int input() { cout<<"Please Enter an octal number:"; cin>>T4Tutorials_Octal; } int show() { int decimalnumber=0; for(count=0;T4Tutorials_Octal>0;count++) { rem = T4Tutorials_Octal%10; decimalnumber = decimalnumber+ rem*pow(8,count); T4Tutorials_Octal=T4Tutorials_Octal/10; } cout<<"decimal equivalent is"<<decimalnumber; } }; int main() { c obj; obj.input(); obj.show(); } |
Output
Please Enter an octal number: 9
decimal equivalent is 9
