What happens when you attempt to compile and run the following code?
#include
using namespace std;
int fun(int x) {
return 2*x;
}
int main(){
int i;
i = fun(0.5) || fun(0);
cout << i;
return 0;
}
What is the output of the program?
#include
using namespace std;
class BaseC
{
int i;
public:
BaseC() { i=?1;}
BaseC(int i) { i=i; }
void seti(int a) { i = a; };
void Print() { cout << i; }
};
int main()
{
BaseC *o = new BaseC();
o?>seti(10);
o?>Print();
}
