1. Which of the following 'C' type is not a primitive data structure?

int

float

char

none of these

2. A declaration "short int" is used for variables

which have a short duration in a program

which have short names

which may require less storage than normal integers

all of these

3. The declaration "unsigned u" indicates u is a/an

unsigned character

unsigned integer

character

none of' these

4. An external variable

is globally accessible by all functions

has a declaration

will be initialized to 0 if not initialized

all of these

5. Consider the declaration char street[10] = "abcdefghi"; Choose the correct remark(s)

&street and street will have different values

&street is meaningless

&street+1 and street+1 will have the same values

None of the above

6. A file is preferable to an array of structures because

file lives even after the program that created it terminates

memory space will not be wasted

there are many system tools to manipulate files

All of the abone

7. Choose the correct statements

Array stores data of the same type

Array can be a part of a structure

Array of structure is allowed

All of the above

8. Pick the correct answers if x is an one dimensional array, then

&x[ i ] is same as x + i - 1

*(x + 1) is same as *(&x [ i ])

*(x + i) is same as x[ i ]

both (b) & (c)

9. While sorting a set of names, representing the names as an array of pointers is preferable to representing the names as a two dimensional array of characters because

storage needed will be proportional to the size of the data

execution will be faster

swapping process becomes easier and faster

All of the above

10. If arr is a two dimensional array of 10 rows and 12 columns, then arr (5) logically points to the

sixth row

Fifth row

fifth column

sixth column
