CBSE Class 11 Computer Science Worksheet Set J Solved

1. What is the difference between one-dimensional array and two-dimensional array? 

2. What do you mean by Unsized array initialization? Give any example. 

3. Consider the following array declaration:

int N[10][20];

i) Find the number of elements in the array.
ii) Find the total number of bytes required to store the array.

4. What output does the following code fragment produce:
int a[4], i;
for(i=0 ; i<4; i++)
a[i] = 5 * i;
for(i=0; i<4; i++)
cout<
5. Write a program to accept a matrix C of size m x n of integers and display its border elements in matrix form.

6. Write a program to accept 5 integers to an array. Sort the array elements in ascending order and display the sorted array.

7. Write a program to accept 5 strings, reverse and store each string in the same array and display the resultant strings.

8. Write a program to accept a string and covert uppercase letters to lowercase and vice versa. Display the resultant string.

9. Write a program to accept an array of „n‟ integers. Accept another integer from the user and check whether that integer is present in the array or not and display proper message.

VALUE POINTS 

1. One-Dimensional Arrays(contains finite homogeneous elements) with example  Two-Dimensional Arrays (contains elements each of which is an array) with example

2. Unsized array initialization -The size of first dimension can be skipped in array initialization. Any example.
