以下是九大排序算法的 C 语言代码实现以及输入输出:
1. 冒泡排序
```c
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;
}
}
}
}
int main() {
int n;
scanf("%d", &n);
int arr[n];
for (int i = 0; i < n; i++) {
scanf("%d", &arr[i]);
}
bubbleSort(arr, n);
for (int i = 0; i < n; i++) {
printf("%d ", arr[i]);
}
return 0;
}
```
2. 选择排序
```c
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[minIndex];
arr[minIndex] = arr[i];
arr[i] = temp;
}
}
int main() {
int n;
scanf("%d", &n);
int arr[n];
for (int i = 0; i < n; i++) {
scanf("%d", &arr[i]);
}
selectionSort(arr, n);
for (int i = 0; i < n; i++) {
printf("%d ", arr[i]);
}
return 0;
}
```
3. 插入排序
```c
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;
}
}
int main() {
int n;
scanf("%d", &n);
int arr[n];
for (int i = 0; i < n; i++) {
scanf("%d", &arr[i]);
}
insertionSort(arr, n);
for (int i = 0; i < n; i++) {
printf("%d ", arr[i]);
}
return 0;
}
```
4. 希尔排序
```c
void shellSort(int arr[], int n) {
for (int gap = n/2; gap > 0; gap /= 2) {
for (int i = gap; i < n; i++) {
int temp = arr[i];
int j;
for (j = i; j >= gap && arr[j-gap] > temp; j -= gap) {
arr[j] = arr[j-gap];
}
arr[j] = temp;
}
}
}
int main() {
int n;
scanf("%d", &n);
int arr[n];
for (int i = 0; i < n; i++) {
scanf("%d", &arr[i]);
}
shellSort(arr, n);
for (int i = 0; i < n; i++) {
printf("%d ", arr[i]);
}
return 0;
}
```
5. 归并排序
```c
void merge(int arr[], int l, int m, int r) {
int n1 = m - l + 1;
int n2 = r - m;
int L[n1], R[n2];
for (int i = 0; i < n1; i++) {
L[i] = arr[l+i];
}
for (int j = 0; j < n2; j++) {
R[j] = arr[m+1+j];
}
int i = 0, j = 0, k = l;
while (i < n1 && j < n2) {
if (L[i] <= R[j]) {
arr[k] = L[i];
i++;
} else {
arr[k] = R[j];
j++;
}
k++;
}
while (i < n1) {
arr[k] = L[i];
i++;
k++;
}
while (j < n2) {
arr[k] = R[j];
j++;
k++;
}
}
void mergeSort(int arr[], int l, int r) {
if (l < r) {
int m = l + (r-l)/2;
mergeSort(arr, l, m);
mergeSort(arr, m+1, r);
merge(arr, l, m, r);
}
}
int main() {
int n;
scanf("%d", &n);
int arr[n];
for (int i = 0; i < n; i++) {
scanf("%d", &arr[i]);
}
mergeSort(arr, 0, n-1);
for (int i = 0; i < n; i++) {
printf("%d ", arr[i]);
}
return 0;
}
```
6. 快速排序
```c
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++;
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 quickSort(int arr[], int low, int high) {
if (low < high) {
int pi = partition(arr, low, high);
quickSort(arr, low, pi-1);
quickSort(arr, pi+1, high);
}
}
int main() {
int n;
scanf("%d", &n);
int arr[n];
for (int i = 0; i < n; i++) {
scanf("%d", &arr[i]);
}
quickSort(arr, 0, n-1);
for (int i = 0; i < n; i++) {
printf("%d ", arr[i]);
}
return 0;
}
```
7. 堆排序
```c
void heapify(int arr[], int n, int i) {
int largest = i;
int l = 2*i + 1;
int r = 2*i + 2;
if (l < n && arr[l] > arr[largest]) {
largest = l;
}
if (r < n && arr[r] > arr[largest]) {
largest = r;
}
if (largest != i) {
int temp = arr[i];
arr[i] = arr[largest];
arr[largest] = temp;
heapify(arr, n, largest);
}
}
void heapSort(int arr[], int n) {
for (int i = n/2-1; i >= 0; i--) {
heapify(arr, n, i);
}
for (int i = n-1; i > 0; i--) {
int temp = arr[0];
arr[0] = arr[i];
arr[i] = temp;
heapify(arr, i, 0);
}
}
int main() {
int n;
scanf("%d", &n);
int arr[n];
for (int i = 0; i < n; i++) {
scanf("%d", &arr[i]);
}
heapSort(arr, n);
for (int i = 0; i < n; i++) {
printf("%d ", arr[i]);
}
return 0;
}
```
8. 计数排序
```c
void countingSort(int arr[], int n) {
int max = arr[0];
for (int i = 1; i < n; i++) {
if (arr[i] > max) {
max = arr[i];
}
}
int count[max+1];
for (int i = 0; i <= max; i++) {
count[i] = 0;
}
for (int i = 0; i < n; i++) {
count[arr[i]]++;
}
for (int i = 1; i <= max; i++) {
count[i] += count[i-1];
}
int output[n];
for (int i = n-1; i >= 0; i--) {
output[count[arr[i]]-1] = arr[i];
count[arr[i]]--;
}
for (int i = 0; i < n; i++) {
arr[i] = output[i];
}
}
int main() {
int n;
scanf("%d", &n);
int arr[n];
for (int i = 0; i < n; i++) {
scanf("%d", &arr[i]);
}
countingSort(arr, n);
for (int i = 0; i < n; i++) {
printf("%d ", arr[i]);
}
return 0;
}
```
9. 桶排序
```c
void bucketSort(int arr[], int n, int bucketSize) {
int max = arr[0];
int min = arr[0];
for (int i = 1; i < n; i++) {
if (arr[i] > max) {
max = arr[i];
}
if (arr[i] < min) {
min = arr[i];
}
}
int bucketCount = (max-min)/bucketSize + 1;
int buckets[bucketCount][bucketSize];
int count[bucketCount];
for (int i = 0; i < bucketCount; i++) {
count[i] = 0;
}
for (int i = 0; i < n; i++) {
int bucketIndex = (arr[i]-min)/bucketSize;
buckets[bucketIndex][count[bucketIndex]] = arr[i];
count[bucketIndex]++;
}
int k = 0;
for (int i = 0; i < bucketCount; i++) {
insertionSort(buckets[i], count[i]);
for (int j = 0; j < count[i]; j++) {
arr[k] = buckets[i][j];
k++;
}
}
}
int main() {
int n;
scanf("%d", &n);
int arr[n];
for (int i = 0; i < n; i++) {
scanf("%d", &arr[i]);
}
bucketSort(arr, n, 5);
for (int i = 0; i < n; i++) {
printf("%d ", arr[i]);
}
return 0;
}
```
