Chapter:08 (Arrays and Strings)

Question 1:

What is an Array in C language?

A group of elements of same data type. An array contains more than one element Array elements are stored in memory in continuous or contiguous locations All the above

Question 2:

What are the Types of Arrays?

int, long, float, double struct, enum char All the above

Question 3:

An array Index starts with.?

-1 0 1 2

Question 4:

What is the output of C Program.?
int main() { int a[] = {1,2,3,4}; int b[4] = {5,6,7,8};
printf("%d,%d", a[0], b[0]); }?

1,5 2,6 0 0 Compiler error

Question 5:

What is an array Base Address in C language?

Base address is the address of 0th index element An array b[] base address is &b[0] An array b[] base address can be printed with printf("%d", b); All the above

Question 6:

Which of these best describes an array?

A data structure that shows a hierarchical behaviour Container of objects of similar types Arrays are immutable once initialised Array is not a data structure

Question 7:

How do you initialize an array in C?

int arr[3] = (1,2,3); int arr(3) = {1,2,3}; int arr[3] = {1,2,3}; int arr(3) = (1,2,3);

Question 8:

What is the output of the following piece of code?
public class array
{
public static void main(String args[])
{
int []arr = {1,2,3,4,5};

System.out.println(arr[4]); }
}

3 and 5 5 and 3 2 and 4 4 and 2

Question 9:

When does the ArrayIndexOutOfBoundsException occur?

Compile-time Run-time Not an error Not an exception at all

Question 10:

What are the advantages of arrays?

Objects of mixed data types can be stored Elements in an array cannot be sorted Index of first element of an array is 1 Easier to store elements of same data type

Question 11:

What are the disadvantages of arrays?

Data structure like queue or stack cannot be implemented There are chances of wastage of memory space if elements inserted in an array are lesser than the allocated size Index value of an array can be negative Elements are sequentially accessed

Question 12:

Assuming int is of 4bytes, what is the size of int arr[15];?

15 19 11 60
