Sort an Array of Numbers in Ascending Order in C++

In this exercise, you will implement a program that sorts an array of numbers in ascending order. Sorting is one of the most fundamental operations in programming, and there are several algorithms to achieve this, such as Bubble Sort, Selection Sort, and Quick Sort. For this exercise, you will focus on using a simple sorting algorithm to reorder the numbers from the smallest to the largest.

Sorting an array allows for better organization of data, easier searching, and more efficient algorithms. This problem is commonly encountered in various fields, from organizing lists of names to processing large datasets.

You'll create a C++ program that sorts an array of numbers in increasing order and then prints the sorted array.

Objective

1. Create a function that takes an array and its size as input.
2. Implement a sorting algorithm to rearrange the numbers in ascending order.
3. You can use a simple sorting algorithm such as Bubble Sort.
4. Print the sorted array to verify the result.
5. Ensure that the output displays the numbers from the smallest to the largest.

Create a program that sorts an array of numbers from smallest to largest.

Example C++ Exercise

 Copy C++ Code 
#include <iostream> // Include iostream for input and output
using namespace std; // Use the standard namespace

// Function to sort an array in ascending order using Bubble Sort
void sortArray(int arr[], int size) {
    // Loop through each element in the array
    for (int i = 0; i < size - 1; i++) {
        // Loop through the array again, up to the last unsorted element
        for (int j = 0; j < size - i - 1; j++) {
            // If the current element is greater than the next, swap them
            if (arr[j] > arr[j + 1]) {
                // Swap the elements
                int temp = arr[j];
                arr[j] = arr[j + 1];
                arr[j + 1] = temp;
            }
        }
    }
}

// Function to print the elements of the array
void printArray(int arr[], int size) {
    // Loop through the array and print each element
    for (int i = 0; i < size; i++) {
        cout << arr[i] << " "; // Print each number followed by a space
    }
    cout << endl; // Print a newline after the array
}

int main() {
    // Define an array of numbers to be sorted
    int numbers[] = {34, 12, 5, 9, 27, 43};
    int size = sizeof(numbers) / sizeof(numbers[0]); // Calculate the size of the array

    // Call the sorting function
    sortArray(numbers, size);

    // Print the sorted array
    cout << "Sorted array: ";
    printArray(numbers, size);

    return 0; // End of program
}

 Output

Sorted array: 5 9 12 27 34 43
