Class 10 Computer Chapter 4 Solved Exercise

The solved exercise for Chapter 4 comprises detailed answers to multiple-choice questions, short answer questions, and long answer questions. Here’s a breakdown:

1. Multiple Choice Questions (MCQs)

The MCQs test students’ understanding of key concepts like arrays, loops, and their functionalities. Examples include:

• An array is a __________ structure. (Correct answer: Data)
• Array elements are stored at ________ memory locations. (Correct answer: Contiguous)

These questions help clarify fundamental terms and syntax.

2. Short Answer Questions

Examples of Questions and Answers:

• Define Array:
  An array is a data structure that holds multiple values of the same type, stored at consecutive memory locations.
  Syntax: Data_type array_name[N] = {value1, value2, ...}
• What is the importance of loops in arrays?
  Loops allow efficient manipulation of arrays, enabling reading, writing, and processing of multiple elements systematically.

3. Long Answer Questions

Example:

Explain “For Loop” in Detail:
The for loop is a control structure that repeats a statement or block of code a fixed number of times. Its syntax is:

for (initialization; condition; increment/decrement) {  
   // Code block to execute  
}

The solved exercise provides examples and flowcharts to make this concept easier to grasp.

4. Programming Exercises
