SECTION B (60 Marks)
Attempt any four questions from this section. Write all the programs in Java BlueJ environment
and clearly explain the steps using the mnemonics and comments wherever required.
1. Write a program to initialize an array of 5 names and initialize another array with their
respective phone numbers. Search for a name input by the user, in the list. If found, display
“Search Successful” and print the name along with the phone number, otherwise display “Name
not enlisted. Try other names”. [ 15 ]
2. Write a program to find the sum of the series; S = 1 + x + x2 + ............... + xn. [ 15 ]
3. Write a program that doubles every element of an array A [4] [4]. [ 15 ]

employee for the following allowances and deduction. Use meaningful variables. [15 ]
5. Write a program to generate all Armstrong numbers between 100 and 500. An Armstrong
number is one which is equal to the cubes of each of its digits. E.g. 153 = 13 + 53 + 33. [ 15 ]
