Sample Program Code – High-Performance Computing in C++

#include 
#include 
#include 

using namespace std;

// Function to swap two elements
void swap(int& a, int& b)
{
    int temp = a;
    a = b;
    b = temp;
}

// Function to perform bubble sort
void bubbleSort(vector& arr)
{
    int n = arr.size();
    for (int i = 0; i < n-1; i++)
    {
        for (int j = 0; j < n-i-1; j++) { if (arr[j] > arr[j+1])
                swap(arr[j], arr[j+1]);
        }
    }
}

// Function to perform selection sort
void selectionSort(vector& arr)
{
    int n = arr.size();
    for (int i = 0; i < n-1; i++)
    {
        int minIndex = i;
        for (int j = i+1; j < n; j++)
        {
            if (arr[j] < arr[minIndex])
                minIndex = j;
        }
        swap(arr[i], arr[minIndex]);
    }
}

// Function to perform insertion sort
void insertionSort(vector& arr)
{
    int n = arr.size();
    for (int i = 1; i < n; i++) { int key = arr[i]; int j = i - 1; while (j >= 0 && arr[j] > key)
        {
            arr[j+1] = arr[j];
            j = j - 1;
        }
        arr[j+1] = key;
    }
}

// Function to print the array
void printArray(vector& arr)
{
    int n = arr.size();
    for (int i = 0; i < n; i++)
    {
        cout << arr[i] << ' ';
    }
    cout << endl;
}

int main()
{
    vector arr = {10, 7, 8, 9, 1, 5};
    
    cout << 'Original Array: ';
    printArray(arr);
    
    // Bubble Sort
    bubbleSort(arr);
    cout << 'Sorted Array using Bubble Sort: ';
    printArray(arr);
    
    // Selection Sort
    selectionSort(arr);
    cout << 'Sorted Array using Selection Sort: ';
    printArray(arr);
    
    // Insertion Sort
    insertionSort(arr);
    cout << 'Sorted Array using Insertion Sort: ';
    printArray(arr);
    
    return 0;
}

Example Output:

Original Array: 10 7 8 9 1 5
Sorted Array using Bubble Sort: 1 5 7 8 9 10
Sorted Array using Selection Sort: 1 5 7 8 9 10
Sorted Array using Insertion Sort: 1 5 7 8 9 10

Example Detailed Explanation:

In this program, we have implemented three advanced sorting algorithms: bubble sort, selection sort, and insertion sort.

1. Bubble Sort: This algorithm compares adjacent elements and swaps them if they are in the wrong order. The process is repeated until the array is sorted.

2. Selection Sort: This algorithm divides the array into two parts: sorted and unsorted. It repeatedly selects the minimum element from the unsorted part and swaps it with the first element of the unsorted part. This process is repeated until the array is sorted.

3. Insertion Sort: This algorithm iterates through the array and for each element, it compares it with the previous elements and inserts it at the correct position. This is done by shifting the elements greater than the key element to the right.

The program starts by initializing an array with some elements. It then calls the bubbleSort() function to sort the array using bubble sort. The sorted array is printed using the printArray() function. Similarly, the program calls the selectionSort() and insertionSort() functions to sort the array using selection sort and insertion sort, respectively. The sorted arrays are printed after each sorting algorithm.

The program demonstrates the functionality and logic of each sorting algorithm. It provides an example of sorting an array in ascending order using three different algorithms. The output shows the original array and the sorted array for each sorting algorithm. The program is well-documented and follows best practices in C++ for high-performance computing.
