统计整数n的各个位上出现数字1、2、3的次数，并通过外部（全局）变量c1、c2、c3返回主函数。
例如，当n=123114350时，结果应该为：c1=3 c2=1 c3=2。
#includeint c1,c2,c3;
void fun(long n)
{
c1 = c2 = c3 = 0;
while (n)
{
/************found************/
switch([填空1])
{
case 1: c1++; break;
/************found************/
case 2: c2++;[填空2]
case 3: c3++;
}
n /= 10;
}
}
main()
{
int n=123114350;
fun(n);
printf(\nn=%d c1=%d c2=%d c3=%d\n,n,c1,c2,c3); }
