 Question 1
Consider the following program
{
int x=1;
printf("%d",(*char(char*)&x));
} 
Assuming required header files are included and if the machine in which this program is executed is little endian, then the output will be
 A 0 B 99999999 C 1 D unpredictable

 Question 2
Consider the following declaration :
 structaddr {
char city;
char street;
int pin;
};
struct {
char name;
int gender;
} person, *kd = &person;
Then $^{\star}(k d->\text { name }+2)$ can be used instead of:
 A person.name+2 B $k d->(\text { name }+2)$ C $*((* k d) . \text { name }+2)$ D either (A) or(B), not (C)

 Question 3
If a variable can take only integral values from 0 to n, where n is an integer, then the variable can be represented as a bit-field whose width is (the log in the answer are to the base 2, and $\lceil\log n\rceil$ means the floor of $\log_{}{n}$ )
 A $\left \lceil \log (n) \right \rceil + 1 \text{ bits}$ B $\left \lceil \log (n-1) \right \rceil + 1 \text{ bits}$ C $\left \lceil \log (n+1) \right \rceil + 1\text{ bits}$ D None of the above

 Question 5
Considering the following table in a relational database :
$\begin{array}{|c|c|c|c|} \hline \text { Last Name } & \text { Rank } & \text { Room } & \text { Shift } \\ \hline \text { Smith } & \text { Manager } & 234 & \text { Morning } \\ \hline \text { Jones } & \text { Custodian } & 33 & \text { Afternoon } \\ \hline \text { Smith } & \text { Custodian } & 33 & \text { Evening } \\ \hline \text { Doe } & \text { Clerical } & 222 & \text { Morning } \\ \hline \end{array}$
According to the data shown in the table, which of the following could be a candidate key of the table?
 A {Last Name} B {Room} C {Shift} D {Room, Shift}
