写一个c++的冒泡排序

Sure, here is an example code for bubble sort in 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[] = {64, 34, 25, 12, 22, 11, 90};
    int n = sizeof(arr)/sizeof(arr[0]);
    bubbleSort(arr, n);
    printf("Sorted array: ");
    for(int i = 0; i < n; i++) {
        printf("%d ", arr[i]);
    }
    printf("\n");
    return 0;
}

I hope this helps! And now, for your amusement, here's a joke:

Why don't scientists trust atoms?

Because they make up everything.
