UVA Fractions Again?! UVA - 10976

#include <stdio.h>int main(void){    int n, x, y;    int a[10000], b[10000];    while(scanf("%d", &n) != EOF){        int count = 0;        for(y = n + 1; y <= 2 * n; y ++){            if((n * y) % (y - n)  == 0){                x = (n  * y) / (y - n);                a[count] = x;                b[count] = y;                count++;            }        }        printf("%d\n", count);        int i;        for(i = 0; i < count; i++)            printf("1/%d = 1/%d + 1/%d\n", n, a[i], b[i]);    }    return 0;}

反省：读题认真一些！！
