1. 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

2. 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

3. 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)

4. 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

5. 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

6. A set of names can be represented as a

two-dimensional array of characters

one-dimensional array of strings

one-dimensional array of pointers to character

All of above

7. Choose the correct statements

Strictly speaking C supports 1-dimensional arrays only

An array element may be an array by itself

Array elements need not occupy contiguous memory locations

Both (a) and (b)

8. Choose the statement that best defines an array

It is a collection of items that share a common name

It is a collection of items that share a common name and occupy consecutive memory location

It is a collection of items of the same type and storage class that share a common name and occupy consecutive memory locations

None of the above

9. If n has the value 3, then the statement a [++n] = n++ ;

assigns 3 to a [5]

assigns 4 to a [5]

assigns 4 to a [4]

what is assigned is compiler-dependent

10. C does no automatic array bound checking. This is

true

false

C's asset

C's shortcoming
