1. What will be the output of the following program? #include<iostream.h> class Number { int Num; public: Number(int x = 0) { Num = x; } void Display(void) { cout<< Num; } void Modify(); }; void Number::Modify() { int Dec; Dec = Num % 13; Num = Num / 13; if(Num > 0 ) Modify() ; if(Dec == 10) cout<< "A" ; else if(Dec == 11) cout<< "B" ; else if(Dec == 12) cout<< "C" ; else if(Dec == 13) cout<< "D" ; else cout<< Dec ; } int main() { Number objNum(130); objNum.Modify(); return 0; }
