Subject : Computer Science

Period: 3rd

Topic: Array in C Programming

School: ABC School

Class: 10

Unit: Seven

Time: 15 min

No. of Students: 20

Specific Objectives

By the end of this brief lesson, students should be able to:

• Understand the concept of arrays in C programming.
• Declare, initialize, and access elements in an array.

Teaching Materials

• Whiteboard and markers
• Quick access to a C compiler for live coding demonstration

Teaching Learning Activity

Introduction (3 minutes):

• Briefly review the concept of variables.
• Introduce the need for handling multiple values efficiently.
• Explain that arrays are collections of similar elements stored in contiguous memory locations.
• The array is the simplest data structure where each data element can be randomly accessed by using its index number.

Declaration and Initialization (5 minutes):

• Show the syntax for declaring an array and initializing it.
• Syntax: data_type array_name[array_size]; //Declaration of array Example: int marks[5];

• marks[0]=80;//initialization of array
• marks[1]=60;
• marks[2]=70;
• marks[3]=85;
• marks[4]=75;

• Declaration with Initialization:
• int numbers[5] = {1, 2, 3, 4, 5};

Accessing Array Elements (3 minutes):

• Explain how to access individual elements using index notation.

int x = numbers[2]; // Access the third element (index 2) of the array

Code Demonstration (4 minutes):

Quickly demonstrate a simple code example on the whiteboard.

1. include <stdio.h>

int main() {

   int numbers[5] = {1, 2, 3, 4, 5};

   for (int i = 0; i < 5; i++) {
       printf("Element %d: %d\n", i, numbers[i]);
   }

   return 0;

}

Conclusion (2 minutes):

• Summarize the key points: Arrays store multiple values of the same type.
• Encourage students to practice declaring, initializing, and accessing arrays.

Evaluation

• What is array? How to declare and initialize array in c?
• Write simple program of array in c ?
