What will the following
#inc1ude <iostream>
using namespace std;
class Package
{
private:
int value;
public:
Package()
{ value = 7; cout ≪ value ≪ endl; }
Package(int v)
{ value = v; cout ≪ value ≪ endl; }
-Package()
{ cout ≪ value ≪ endl; }
};
int main()
{
Package obj1(4);
Package obj2;
Package obj3(2);
return 0;
}

You must write the code. - Yes, you can convert from string to integer stoi ( string). - In addition to the constructors, you should supply a set of getters (Accessors) getH, getM getS - In addition to that, add mutators that allow the individual setting of Hours, Minutes and Seconds: setH(int), setM ( int ) setS( int ) Include this setter ( Mutator) setTime( int NumSeconds); - So if I call setTime( 7673) you would know that that is: -- hours, -- minutes and -- seconds seconds = 53 7673 % 60…arrow_forward#include<stdio.h> #include<stdarg.h> void fun1(int num, ...); void fun2(int num, ...); int main() { fun1(1, "Apple", "Boys", "Cats", "Dogs"); fun2(2, 12, 13, 14); return 0; } void fun1(int num, ...) { char *str; va_list ptr; va_start(ptr, num); str = va_arg(ptr, char *); printf("%s ", str); } void fun2(int num, ...) { va_list ptr; va_start(ptr, num); num = va_arg(ptr, int); printf("%d", num); }.arrow_forward
