ICSE Class 10 Computer Applications: Important Programs & Sample Questions

Computer Applications is one of the most interesting and practical subjects in ICSE Class 10. Unlike purely theoretical subjects, this one demands logic, practice, and problem-solving skills. Students are expected to not only understand programming concepts but also apply them while writing actual code. For many, this subject feels scoring, but only if the basics are strong and regular practice is maintained.

With the 2026 board exams in mind, students are already looking at different resources such as the icse class 10 question bank 2026, standard icse class 10 books, and various guides to make sure their preparation is complete. Among all subjects, Computer Applications stands out because it requires hands-on practice of programs and clarity of logic.

In this blog, we will go over the important programs, discuss common sample questions, and also share some tips on how to prepare effectively using the right resources, such as an icse class 10 computer book or an icse sample paper class 10.

Why Computer Applications is Important?

The subject holds a weightage of 100 marks, with 80 marks for the written exam and 20 marks for internal assessment. The written paper includes both theoretical and practical programming-based questions. Since programs form the backbone of this subject, students who practice them regularly can easily score well.

Computer Applications is also a subject that directly connects with higher studies and future careers. Learning Java programming, which is the language prescribed by ICSE, gives students a foundation for advanced computer science courses. That is why mastering important programs at this level is a huge advantage.

Commonly Asked Program Types

Every year, some types of programs are asked again and again in the ICSE Class 10 Computer Applications exam. These usually include conditional statements like if-else, looping programs using for or while, and string handling tasks such as reversing or checking palindromes. Mathematical problems like factorial, prime numbers, GCD, and Fibonacci are also very common. Array-based questions such as sorting, searching, and sums, along with programs using functions and recursion, often appear. Practicing these from an icse class 10 computer book builds strong confidence.

Sample Questions for Practice

To get a sense of what the actual exam may look like, here are some sample-style questions inspired by past papers and practice sets:

1. Write a program to input a number and check whether it is an Armstrong number or not.

2. Write a program to enter a sentence and count the number of vowels and consonants in it.

3. Write a program to input an array of integers and display the largest and smallest numbers.

4. Write a program to accept a number and print its multiplication table up to 10.

5. Write a program to input two strings and check whether they are anagrams of each other.

6. Write a program using recursion to find the factorial of a number.

7. Write a menu-driven program to calculate the area of a circle, rectangle, and triangle based on user choice.

These examples represent the style and difficulty level that ICSE tends to use. Practicing similar problems from an icse sample paper class 10 can give you the exam-day comfort you need.

Table of Must-Practice Programs

To make things even clearer, here is a table of program categories that every student should practice multiple times before the exam:

This table covers the backbone of Computer Applications in Class 10. If you are confident with these, you can handle most of the exam questions with ease.

How to Prepare Effectively

Preparation for Computer Applications is different from subjects like History or Geography. You cannot simply memorize and reproduce answers. You need to understand logic and be able to write programs independently.

The first step is to build your base using standard icse class 10 books, especially the prescribed textbooks. These explain programming concepts step by step, which is essential for beginners. Once the basics are strong, move on to more advanced practice with an icse class 10 computer book that includes a wide range of solved and unsolved programs.

Next, strengthen your preparation with the icse class 10 question bank 2026. This will give you a collection of important questions and programs categorized by chapters. Working through them helps you identify which areas are frequently tested and which ones need more practice from your side.

Finally, once you have revised the syllabus, test yourself with an icse sample paper class 10. These sample papers simulate the real exam pattern and timing, helping you improve speed and accuracy. Attempting at least two to three full-length sample papers before the board exam is highly recommended.

Tips for Scoring Well in Computer Applications

Success in Computer Applications comes with regular coding practice and attention to detail. Some tips to keep in mind are:

• Always dry-run your program logic with small values before finalizing.

• Indent your code properly and write clear variable names, as neatness matters in board exams.

• Focus on understanding how loops and conditionals work, as they form the base of most questions.

• Revise string and array programs thoroughly, as they are among the most commonly tested topics.

• Use the last few weeks to solve problems from an icse sample paper class 10 or question bank under exam conditions.

These habits will ensure that you not only write correct code but also present it clearly, which is equally important for scoring well.

Final Thoughts

ICSE Class 10 Computer Applications is a subject where you can score high marks with the right preparation strategy. Instead of memorizing programs, focus on understanding the logic and practicing them regularly. Use standard icse class 10 books to strengthen your base, then move on to an icse class 10 computer book for wider practice. To check your readiness, solve papers from the icse class 10 question bank 2026 and attempt an icse sample paper class 10 under timed conditions.

By covering important programs like strings, arrays, recursion, and conditional logic, and by practicing a wide variety of sample questions, you can walk into the exam hall with confidence. Remember, consistency is the real key. A little practice every day is far more effective than rushing in the last moment. With the right resources and regular effort, scoring well in Computer Applications is absolutely achievable.

FAQs
