ICSE 2019 Computer Applications Question Paper for Class 10

About this paper

This is the ICSE Class 10 Computer Applications (Theory) paper for 2019, paper code T19 861. 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 OOP principles, operators, tokens, data type sizes, if-else-if versus switch, types of errors, linear and binary search, call by value and reference, and String and Math methods. In Section B candidates write Java programs for any four of six questions: a ShowRoom discount class, a menu for Unicode values and a number pattern, bubble sort of 15 integers, overloading series(), counting words that start with A, and four-digit tech numbers. This copy has the questions only.

Questions from this paper

1. Write a difference between unary and binary operators.
2. What is the difference between the linear search and the binary search technique?
3. State a difference between call by value and call by reference.
4. Write a program to input 15 integer elements in an array and sort them in ascending order using the bubble sort technique.
5. Write a program to input a sentence, convert it into uppercase, and count and display the total number of words starting with the letter 'A'.
6. A tech number has an even number of digits, and the square of the sum of its two halves equals the number, as in (30 + 25)² = 3025. Write a program to generate and print all four-digit tech numbers.
