判断一个分数是否为无限循环小数

#include <stdio.h>

int main()
{
int remiander[101] = {0};//存放余数
int quotient[101] = {0};

int m;
int n;
printf("please input (m/n)(m < n):\n");
scanf("%d/%d",&m,&n);
printf("m/n 是一个有限不循环小数 0.");
for(i = 1; i <= 100; i++)
{
remainder[m] = i;
m *= 10;
quotient[i] = m / n;
m = m % n;
if(m == 0)
{
for(j = 1; j <= i; j++)
{
printf("%d",quotient[j]);
}
printf("\n");
}
if(remainder[m] != 0)
{
for(j = 1; j <= i; j++)
{
printf("\n\tand it is a infinaite cyclic fraction from %d\n",remainder[m]);
printf("\tdigit to %d digit after decimal point.\n",i);

printf("\n");
break;
