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. 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.

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

Syntax:data_type array_name[array_size]; Example:int marks[5];

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 ?
