What will the variable "age" be in class B?class A {int x;protected:int y;public:int age;A () { age=5; };};class B : public A {string name;public:B () { name="Bob"; };void Print() {cout << name << age;}};
Answer(s): A
What happens when you attempt to compile and run the following code?#include <iostream>#include <string>using namespace std;class complex{double re, im;public:complex() : re(1),im(0.4) {}complex operator?(complex &t);void Print() { cout << re << " " << im; }};complex complex::operator? (complex &t){complex temp;temp.re = this?>re ? t.re;temp.im = this?>im ? t.im;return temp;}int main(){complex c1,c2,c3;c3 = c1 ? c2;c3.Print();}
Answer(s): C
What happens when you attempt to compile and run the following code?#include <iostream>using namespace std;class complex{double re;double im;public:complex() : re(0),im(0) {}complex(double x) { re=x,im=x;};complex(double x,double y) { re=x,im=y;}void print() { cout << re << " " << im;}};int main(){complex c1;c1 = 3.0;c1.print();return 0;}
What happens when you attempt to compile and run the following code?#include <iostream>using namespace std;void fun(int);int main(){int a=0;fun(a);return 0;}void fun(int n){if(n < 2){fun(++n);cout << n;}}
What happens when you attempt to compile and run the following code?#include <iostream>using namespace std;int s(int n);int main(){int a;a = 3;cout << s(a);return 0;}int s(int n){if(n == 0) return 1;return s(n?1)*n;}
