c语言随机生成一个数组并插入排序

生成一个随机数组并进行插入排序的C语言代码如下：

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

void insertionSort(int arr[], int n) {
    int i, key, j;
    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 n, i;
    printf("Enter the size of the array: ");
    scanf("%d", &n);

    int arr[n];
    srand(time(0));
    printf("Generated array: ");
    for (i = 0; i < n; i++) {
        arr[i] = rand() % 100; // 生成0到99之间的随机数
        printf("%d ", arr[i]);
    }
    printf("\n");

    insertionSort(arr, n);

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

    return 0;
}
