用c语言实现分别采用直接插入排序，简单选择排序，冒泡排序，快速排序，归并排序的算法对给 定的线性表进行排序。

下面是使用C语言实现五种排序算法的代码，可以对一个数组进行排序：

#include <stdio.h>

/* 直接插入排序 */
void InsertionSort(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--;
        }
        arr[j + 1] = key;
    }
}

/* 简单选择排序 */
void SelectionSort(int arr[], int n) {
    int i, j, min, temp;
    for (i = 0; i < n - 1; i++) {
        min = i;
        for (j = i + 1; j < n; j++) {
            if (arr[j] < arr[min]) {
                min = j;
            }
        }
        if (min != i) {
            temp = arr[i];
            arr[i] = arr[min];
            arr[min] = temp;
        }
    }
}

/* 冒泡排序 */
void BubbleSort(int arr[], int n) {
    int i, j, temp;
    for (i = 0; i < n - 1; i++) {
        for (j = 0; j < n - i - 1; j++) {
            if (arr[j] > arr[j + 1]) {
                temp = arr[j];
                arr[j] = arr[j + 1];
                arr[j + 1] = temp;
            }
        }
    }
}

/* 快速排序 */
void QuickSort(int arr[], int left, int right) {
    if (left < right) {
        int i = left, j = right, pivot = arr[left];
        while (i < j) {
            while (i < j && arr[j] >= pivot) j--;
            if (i < j) arr[i++] = arr[j];
            while (i < j && arr[i] <= pivot) i++;
            if (i < j) arr[j--] = arr[i];
        }
        arr[i] = pivot;
        QuickSort(arr, left, i - 1);
        QuickSort(arr, i + 1, right);
    }
}

/* 归并排序 */
void Merge(int arr[], int left, int mid, int right) {
    int i, j, k;
    int n1 = mid - left + 1;
    int n2 = right - mid;
    int L[n1], R[n2];
    for (i = 0; i < n1; i++) {
        L[i] = arr[left + i];
    }
    for (j = 0; j < n2; j++) {
        R[j] = arr[mid + 1 + j];
    }
    i = 0;
    j = 0;
    k = left;
    while (i < n1 && j < n2) {
        if (L[i] <= R[j]) {
            arr[k++] = L[i++];
        } else {
            arr[k++] = R[j++];
        }
    }
    while (i < n1) {
        arr[k++] = L[i++];
    }
    while (j < n2) {
        arr[k++] = R[j++];
    }
}

void MergeSort(int arr[], int left, int right) {
    if (left < right) {
        int mid = (left + right) / 2;
        MergeSort(arr, left, mid);
        MergeSort(arr, mid + 1, right);
        Merge(arr, left, mid, right);
    }
}

int main() {
    int arr[] = {3, 1, 4, 1, 5, 9, 2, 6, 5, 3, 5};
    int n = sizeof(arr) / sizeof(arr[0]);

    printf("Original array:\n");
    for (int i = 0; i < n; i++) {
        printf("%d ", arr[i]);
    }

    InsertionSort(arr, n);
    // SelectionSort(arr, n);
    // BubbleSort(arr, n);
    // QuickSort(arr, 0, n - 1);
    // MergeSort(arr, 0, n - 1);

    printf("\nSorted array:\n");
    for (int i = 0; i < n; i++) {
        printf("%d ", arr[i]);
    }
    printf("\n");

    return 0;
