Question

1)What is the output of the following code?
struct someType
{ int a;
int b;
};
void f1(someType &s)
{ s.a = 1;
s.b = 2;
}
someType f2(someType s)
{ someType t;
t = s;
s.a = 3;
return t;
}
int main()
{ someType s1, s2;
f1(s1);
s2 = f2(s1);
cout << s1.a << '-' << s1.b << '-' <<
s2.a << '-' << s2.b << '-' << endl;
return 0;
}

2)

struct dateType {
   int month;
   int day;
   int year;
};

struct employeeType {
   string name;
   dateType birthDate;
   dateType hireDate;
};

employeeType emp;
cout << emp.name << endl;
cout << "   Born " << emp.birthDate.month << "-" << emp.birthDate.day << endl;

QUestion --The following code is used to read in the year each employee was hired. What should be placed in the blank to finish the code?

// Use structures declared above
employeeType employees[10];
for (int i = 0; i < 10; i++)
{
cin >> ___________;
}

Answer 1

Question 1:

Answer :1-2-1-2-

Explanation :

• here s1.a will print 1 then s1.b will print 2
• s1 is passed by references in f1() hence changes will be made in the memory and hence
• s2.a will again print 1 and s2.b will print 2
• and hence the answer

Below screen shows the output

Question 2:

Screen :

Explanation :Here emp.name will be empty and emp.birthDate.month will be 0 and emp.birthDate.day will be 0

======================

Question 3:

employeeType employees[10];
for (int i = 0; i < 10; i++)
{
cin>>employees[i].hireDate.year;
}
