用c语言编程实现冒泡排序

以下是用C语言编程实现冒泡排序的示例代码：

#include <stdio.h>

void bubbleSort(int arr[], int n) {
    int i, j;
    for (i = 0; i < n-1; i++) {
        for (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;
            }
        }
    }
}

int main() {
    int arr[] = {64, 34, 25, 12, 22, 11, 90};
    int n = sizeof(arr)/sizeof(arr[0]);
    bubbleSort(arr, n);
    printf("Sorted array: \n");
    for (int i=0; i < n; i++) {
        printf("%d ", arr[i]);
    }
    return 0;
}

C语言编程实现冒泡排序

可以使用以下代码实现冒泡排序：

#include <stdio.h>

void bubble_sort(int arr[], int n) {
    int i, j, temp;
    for (i = ; i < n - 1; i++) {
        for (j = ; j < n - i - 1; j++) {
            if (arr[j] > arr[j + 1]) {
                temp = arr[j];
                arr[j] = arr[j + 1];
                arr[j + 1] = temp;
            }
        }
    }
}

int main() {
    int arr[] = {5, 2, 8, 3, 1, 6};
    int n = sizeof(arr) / sizeof(arr[]);
    bubble_sort(arr, n);
    for (int i = ; i < n; i++) {
        printf("%d ", arr[i]);
    }
    return ;
}

帮我用C语言编程实现冒泡排序法，选择排序算法，插入排序法，快速排序算法

好的，以下是用C语言实现四种排序算法的代码：

1. 冒泡排序法

#include <stdio.h>

void bubble_sort(int arr[], int n) {
    int i, j, temp;
    for (i = 0; i < n - 1; i++) {
        for (j = 0; j < n - 1 - i; j++) {
            if (arr[j] > arr[j + 1]) {
                temp = arr[j];
                arr[j] = arr[j + 1];
                arr[j + 1] = temp;
            }
        }
    }
}

int main() {
    int arr[] = { 5, 2, 9, 3, 6 };
    int n = sizeof(arr) / sizeof(arr[0]);
    bubble_sort(arr, n);
    printf("Sorted array: ");
    for (int i = 0; i < n; i++) {
        printf("%d ", arr[i]);
    }
    return 0;
}

2. 选择排序算法

#include <stdio.h>

void selection_sort(int arr[], int n) {
    int i, j, min_idx, temp;
    for (i = 0; i < n - 1; i++) {
        min_idx = i;
        for (j = i + 1; j < n; j++) {
            if (arr[j] < arr[min_idx]) {
                min_idx = j;
            }
        }
        temp = arr[i];
        arr[i] = arr[min_idx];
        arr[min_idx] = temp;
    }
}

int main() {
    int arr[] = { 5, 2, 9, 3, 6 };
    int n = sizeof(arr) / sizeof(arr[0]);
    selection_sort(arr, n);
    printf("Sorted array: ");
    for (int i = 0; i < n; i++) {
        printf("%d ", arr[i]);
    }
    return 0;
}

3. 插入排序法

#include <stdio.h>

void insertion_sort(int arr[], int n) {
    int i, j, key;
    for (i = 1; i < n; i++) {
        key = arr[i];
        j = i - 1;
        while (j >= 0 && arr[j] > key) {
            arr[j + 1] = arr[j];
            j = j - 1;
        }
        arr[j + 1] = key;
    }
}

int main() {
    int arr[] = { 5, 2, 9, 3, 6 };
    int n = sizeof(arr) / sizeof(arr[0]);
    insertion_sort(arr, n);
    printf("Sorted array: ");
    for (int i = 0; i < n; i++) {
        printf("%d ", arr[i]);
    }
    return 0;
}

4. 快速排序算法

#include <stdio.h>

void swap(int* a, int* b) {
    int temp = *a;
    *a = *b;
    *b = temp;
}

int partition(int arr[], int low, int high) {
    int pivot = arr[high];
    int i = low - 1;
    for (int j = low; j <= high - 1; j++) {
        if (arr[j] < pivot) {
            i++;
            swap(&arr[i], &arr[j]);
        }
    }
    swap(&arr[i + 1], &arr[high]);
    return (i + 1);
}

void quick_sort(int arr[], int low, int high) {
    if (low < high) {
        int pi = partition(arr, low, high);
        quick_sort(arr, low, pi - 1);
        quick_sort(arr, pi + 1, high);
    }
}

int main() {
    int arr[] = { 5, 2, 9, 3, 6 };
    int n = sizeof(arr) / sizeof(arr[0]);
    quick_sort(arr, 0, n - 1);
    printf("Sorted array: ");
    for (int i = 0; i < n; i++) {
        printf("%d ", arr[i]);
    }
    return 0;
}
