c语言如何将数组排序

以下是两种C语言将数组排序的方法:
1. 冒泡排序
```c
#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[] = {999, 10, 15, 18, 5, 30, 80, 26, 345, -10};
int n = sizeof(arr)/sizeof(arr[0]);
bubbleSort(arr, n);
for (int i = 0; i < n; i++) {
printf("%d ", arr[i]);
}
printf("\n"); return 0;
}
```
2. 插入排序
```c
#include <stdio.h>
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 = j - 1;
}
arr[j+1] = key;
}
}
int main() {
int arr[] = {999, 10, 15, 18, 5, 30, 80, 26, 345, -10};
int n = sizeof(arr)/sizeof(arr[0]);
insertionSort(arr, n);
for (int i = 0; i < n; i++) {
printf("%d ", arr[i]);
}
printf("\n");
return 0;
}
```
