scanf("%d",&number);

printf("Now array a:\n");
for(i=0;i<11;i++)

return 0;}

void sort(int a[])
{int temp1,temp2,number,end,i,j;
end=a[9];
if(number>end)
a[10]=number;
else
{for(i=0;i<10;i++)
{if(a[i]>number)
{temp1=a[i];a[i]=number;}
for(j=i+1;j<11;j++)
{temp2=a[j];a[j]=temp1;temp1=temp2;}
break;
}
}
}

我已经知道该怎么改了 谢谢
