Implementing an Array to Hold 5 Integers in Python, C, and Java

Arrays are fundamental data structures in programming that allow storing multiple values of the same type in a single variable. They are particularly useful when you need to work with a fixed, but relatively small, number of elements, such as holding 5 this article, we will provide examples of how to implement an array to store 5 integers in Python, C, and Java. These examples will cover the declaration of an array, user input, and the display of output values.

1. Python Example

Python provides a simple and elegant way to work with arrays. Here's how you can create an array to hold 5 integers:

# Initialize an array with 5 integersnumbers  [0] * 5# Input 5 integers from the userfor i in range(5):    numbers[i]  int(input("Enter integer {}: ".format(i   1)))# Display the integersprint("Entered integers: ", end"")print(*numbers, sep" ")

2. C Example

In C, arrays are zero-indexed, and you can input 5 integers using a loop. Here’s the code for this task:

#include stdio.hint main() {    int numbers[5];  // Declare an array to hold 5 integers    // Input 5 integers from the user    for (int i  0; i  5; i  ) {        printf("Enter integer %d: ", i   1);        scanf("%d", numbers[i]);    }    // Display the integers    printf("Entered integers: ");    for (int i  0; i  5; i  ) {        printf("%d ", numbers[i]);    }    printf("
");    return 0;}

3. Java Example

Java also provides a straightforward approach to working with arrays. Here’s how to create an array to hold 5 integers using a Scanner for input:

import ;public class Main {    public static void main(String[] args) {        int[] numbers  new int[5];  // Declare an array to hold 5 integers        Scanner scanner  new Scanner();        // Input 5 integers from the user        for (int i  0; i  5; i  ) {            numbers[i]  ();        }        // Display the integers        ("Entered integers: ");        for (int number : numbers) {            (number   " ");        }    }}

Explanation

Array Declaration: Each example declares an array that can hold 5 integers. In C and Java, you explicitly declare the array size. In Python, you can use the * operator with a list to create an array with the desired size.

User Input: A loop is used to gather input from the user and store it in the array. This loop iterates 5 times, requesting one integer per iteration.

Display Output: Another loop is used to print the values stored in the array. This loop iterates through the array and prints each element, separated by a space.

You can choose any of these examples based on your preferred programming language. If you need further assistance or have any questions, feel free to ask!
