下面是一个C语言冒泡排序程序。冒泡排序又称交换排序或“起泡法排序”，它通过将相邻数据进行比较和交换，逐步将一个无序排列列为一个有序序列。请完成这个程序的空白部分。#include＜stdio.h＞int a[10];int i,j,k,t;int b;int main(){printf("Enter date:");for(i=0;i＜=9;i++){scanf("%d",&a[i]);)i=0;b=1;while((i＜9)&&(b==1)){b=0;for(j=9;j＞=i+1;j--){if(a[j-1]＜a[j]){ ____(1)____ ; ____(2)____ }}i++;}printf("output data:")；for(i=0;i＜=9;i++){printf("%4d",a[i];}printf("\n"");}
