好的,这里是一个包括四种排序算法的完整程序实现:
```c++
#include <iostream>
using namespace std;
void bubbleSort(int arr[], int n) {
for (int i = 0; i < n - 1; i++) {
for (int j = 0; j < n - i - 1; j++) {
if (arr[j] > arr[j + 1]) {
int temp = arr[j];
arr[j] = arr[j + 1];
arr[j + 1] = temp;
}
}
}
}
void selectionSort(int arr[], int n) {
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;
}
}
int temp = arr[i];
arr[i] = arr[minIndex];
arr[minIndex] = temp;
}
}
void insertionSort(int arr[], int n) {
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--;
}
arr[j + 1] = key;
}
}
void quickSort(int arr[], int low, int high) {
if (low < high) {
int pivot = partition(arr, low, high);
quickSort(arr, low, pivot - 1);
quickSort(arr, pivot + 1, high);
}
}
int partition(int arr[], int low, int high) {
int pivot = arr[high];
int i = low - 1;
for (int j = low; j < high; j++) {
if (arr[j] < pivot) {
i++;
int temp = arr[i];
arr[i] = arr[j];
arr[j] = temp;
}
}
int temp = arr[i + 1];
arr[i + 1] = arr[high];
arr[high] = temp;
return i + 1;
}
void printArray(int arr[], int n) {
for (int i = 0; i < n; i++) {
cout << arr[i] << " ";
}
cout << endl;
}
int main() {
int arr[] = {5, 2, 7, 1, 9, 6, 8, 3, 4};
int n = sizeof(arr) / sizeof(arr[0]);
cout << "Original array: ";
printArray(arr, n);
bubbleSort(arr, n);
cout << "Array sorted using bubble sort: ";
printArray(arr, n);
int arr2[] = {5, 2, 7, 1, 9, 6, 8, 3, 4};
selectionSort(arr2, n);
cout << "Array sorted using selection sort: ";
printArray(arr2, n);
int arr3[] = {5, 2, 7, 1, 9, 6, 8, 3, 4};
insertionSort(arr3, n);
cout << "Array sorted using insertion sort: ";
printArray(arr3, n);
int arr4[] = {5, 2, 7, 1, 9, 6, 8, 3, 4};
quickSort(arr4, 0, n - 1);
cout << "Array sorted using quick sort: ";
printArray(arr4, n);
return 0;
}
```
希望这个程序可以帮助到你!
