关于冒泡排序

#include <stdio.h>#include <string.h>//sizeof(数组名)是string.h里面的函数int main(){//冒泡int a[] ={1,0,9,6,7,3,7,5,8};int temp;

int length = sizeof(a) / sizeof(int) ;printf("length=%d",length);for(int i = length-1 ;i >= 0;i--){for(int j = 0;j < i;j++){if(a[j] > a[j+1]){temp = a[j];a[j] = a[j + 1];a[j + 1] = temp;}}}for(int i = 0;i < length;i++){printf("%d\n",a[i]);}return 0;}
