ICSE 2018 Computer Applications Solved Paper for Class 10

About this paper

This is the ICSE Class 10 Computer Applications (Theory) paper from the 2018 examination, with an answer written under every question and a full Java program for each Section B question. It is a two-hour paper with fifteen minutes of reading time, and its two sections carry 40 and 60 marks. Section A has three compulsory questions of two-mark parts on abstraction, searching and sorting, isUpperCase() and toUpperCase(), access specifiers, loops, Math and String methods and converting if-else to switch. In Section B candidates attempt any four of six programs: a RailwayTicket class, Pronic numbers, capitalising the first letter of each word, overloading volume(), a letter-pattern menu, and the average and deviation of students' total marks.

Questions from this paper

1. Define abstraction.
2. State the difference between a while loop and a do-while loop.
3. Write two characteristics of a constructor.
4. Write a program to input a number and check whether it is a Pronic number, that is, the product of two consecutive integers (for example, 12 = 3 × 4).
5. Write a program to accept a string in lower case and change the first letter of every word to upper case, so that "we are in cyber" becomes "We Are In Cyber".
6. Write a program to accept the names and total marks of N students in two arrays, then print the average of the total marks and each student's deviation from the average.
