C++ array sort method

#include <iostream>
#include <algorithm>

int main() {
    const int size = 5;
    int arr[size] = {4, 2, 7, 1, 5};

    std::cout << "Original array: ";
    for (int i = 0; i < size; ++i)
        std::cout << arr[i] << " ";
    std::cout << std::endl;

    std::sort(arr, arr + size);

    std::cout << "Sorted array: ";
    for (int i = 0; i < size; ++i)
        std::cout << arr[i] << " ";
    std::cout << std::endl;

    return 0;
}

1. Include necessary headers: Include the <iostream> and <algorithm> headers, which provide input/output stream functionality and algorithms like std::sort, respectively.

2. Define main function: Start the main function, the entry point of the program.

3. Initialize array: Declare a constant integer size and an integer array arr of that size, with initial values.

4. Display original array: Use a for loop to iterate through the elements of the array and display them on the console.

5. Sort the array: Use std::sort to sort the array in ascending order. Pass the beginning and end iterators of the array as arguments.

6. Display sorted array: Use a for loop again to iterate through the sorted array and display its elements on the console.

7. Return 0: The main function returns 0 to indicate successful execution.
