怎么趟数一次没变啊……

#include <stdio.h>
#include <stdlib.h>
#define size 10
int main()
{
int t;
int a[size] = {0};
int i,j,x,y;
for(i = 0;i < size; i++){
scanf("%d",&a[i]);
}
for(i = 0;i < size; i++){
printf(" %d",a[i]);
}
printf("\n");
for(i = 0;i < size - 1;i++){
for(j = 0;j < size - 1 -i;j++){
if(a[j]>a[j+1]){
t=a[j];
a[j]=a[j+1];
a[j+1]=t;
y++;
}
}
x++;
}
printf("趟数：%d\n",x);
printf("次数: %d\n",y);
for(i = 0;i < size;i++){
printf(" %d",a[i]);
}
}

x, y要初始化为0
