Class 10 Computer Chapter 5 Solved Notes Topic-Wise

1. Definition of Functions

A function is a block of statements designed to perform a specific task. For example:

• printf: Displays output.
• scanf: Takes user input.

Every program contains a main function, while additional functions can be written and reused multiple times.

Syntax:

return_type function_name(data_type var1, data_type var2, …)  
{  
    // Function Body  
}

2. Types of Functions

Functions are categorized as follows:

• Built-in Functions: Predefined in C Standard Library (e.g., printf, scanf).
• User-Defined Functions: Created by the programmer for specific tasks.

Examples:

• Built-in: Performing mathematical or string operations.
• User-Defined: Calculating the sum of numbers or validating a triangle.

3. Advantages of Functions

Using functions in programming provides the following benefits:

• Reusability: Avoids redundant code by calling functions repeatedly.
• Separation of Tasks: Enables isolated debugging and easier management.
• Complexity Reduction: Divides larger problems into manageable parts.
• Improved Readability: Structured code improves understanding and maintenance.

4. Calling and Defining a Function

To execute a function, it must be called. Here’s the basic structure:

function_name(value1, value2, …);  

A function definition specifies the task it performs, while the return keyword ensures appropriate output.

5. MCQs, Short Questions, and Long Questions

Multiple Choice Questions:

1. Functions are categorized into:
   • (A) Built-in
   • (B) User-defined
   • (C) Both A & B
   • (D) None of these
     Answer: (C)

Short Question:

• Q: What is a function?
  A: A function is a block of statements designed to perform a particular task.

Long Question:

• Q: Explain the types of functions with examples.
  A: Built-in functions like printf and scanf handle standard tasks, while user-defined functions are created for specific needs, like calculating the sum of numbers.

Programming Exercises

To solidify the concepts of functions, here are practical examples from the notes:

Exercise 1: Prime Number Checker

int prime(int n) {
    for (int i = 2; i < n; i++) {
        if (n % i == 0) return 0;
    }
    return 1;
}

This function checks if a number is prime. Calling prime(x) returns 1 if the number is prime or 0 otherwise.

Exercise 2: Sum of Numbers

int digitsSum(int n) {
    int sum = 0;
    for (int i = 0; i <= n; i++) {
        sum += i;
    }
    return sum;
}

This function calculates the sum of all numbers up to the given input.

Exercise 3: Printing a Table

int table(int n) {
    for (int i = 1; i <= 10; i++) {
        printf("%d x %d = %d\n", n, i, n * i);
    }
    return 0;
}

This function prints the multiplication table of the input number.
