Lecture 77:- Demo - Array Declaration

Here's a demo of array declaration in different programming languages:

1. C/C++:

cppCopy code

#include <iostream> int main() {    // Declare an array of integers with a size of 5    int intArray[5];    // Declare an array of characters with an explicit size of 10    char charArray[10];    // Assign values to the elements of the arrays    intArray[0] = 1;    intArray[1] = 2;    charArray[0] = 'H';    charArray[1] = 'i';    // Print the values of the arrays    std::cout << intArray[0] << " " << intArray[1] << std::endl;    std::cout << charArray[0] << charArray[1] << std::endl;    return 0; }

1. Java:

javaCopy code

public class ArrayDemo {    public static void main(String[] args) {        // Declare an array of integers with a size of 5        int[] intArray = new int[5];        // Declare an array of strings with an explicit size of 3        String[] stringArray = new String[3];        // Assign values to the elements of the arrays        intArray[0] = 1;        intArray[1] = 2;        stringArray[0] = "Hello";        stringArray[1] = "World";        // Print the values of the arrays        System.out.println(intArray[0] + " " + intArray[1]);        System.out.println(stringArray[0] + " " + stringArray[1]);    } }

1. Python:

pythonCopy code

# Declare an array of integers intArray = [0, 0, 0, 0, 0] # Declare an array of strings stringArray = ["apple", "banana", "cherry"] # Assign values to the elements of the arrays intArray[0] = 1 intArray[1] = 2 # Print the values of the arrays print(intArray[0], intArray[1]) print(stringArray[0], stringArray[1])

1. JavaScript:

javascriptCopy code

// Declare an array of integers let intArray = [1, 2, 3, 4, 5]; // Declare an array of strings let stringArray = ["apple", "banana", "cherry"]; // Assign values to the elements of the arrays intArray[0] = 10; intArray[1] = 20; // Print the values of the arrays console.log(intArray[0], intArray[1]); console.log(stringArray[0], stringArray[1]);

In all the examples, we declare arrays of different types (integers, characters, strings) and assign values to their elements. Then, we print the values to verify the assignments.
