What is the output of this program?

#include 
    using namespace std;
    struct second
    {
        int p;
        char q;
    };
    int main()
    {
        struct second sec ={30,210};
        struct second *ps =(struct second *)&sec;
        cout << ps->p <<" "<< ps->q;
        return 0;
    }

Correct Option: E

30 F

What will be the output of this program?

#include 
    using namespace std;
    int main()
    {
        struct MansWear 
        {
           string Brand;
           double price;
        };
         MansWear MansWear1, MansWear2;
         MansWear1.Brand = "Peter England";
         MansWear1.price = 999.99;
         cout << MansWear1.Brand << " $ "<MansWear2 = MansWear1;
         MansWear2.price = MansWear2.price / 10;
         cout << MansWear1.Brand << " $ "<< MansWear2.price;
         return 0;
    }

Correct Option: C

We copied the value of MansWear1 into MansWear2 and divide the MansWear2 value by 10, So this is the output.
Peter England $ 999.99
Peter England $ 99.999

What is the output of this program?

#include 
    using namespace std;
    struct T 
    {
        int H;
        int M;
        int S;
    };
    int Seconds(T now);
    int main()
    {
        T t;
        t.H = 6;
        t.M = 3;
        t.S = 15;
        cout << "Total seconds: " << Seconds(t) << endl;
        return 0;
    }
    int Seconds(T now)
    {
        return 3600 * now.H + 60 * now.M + now.S;
    }

Correct Option: A

In this program, we are just converting the given hours and minutes into seconds.
