C语言训练-列出最简真分数序列*

解题思路:  40 的因数有1,2,4,5,8,10,20,40,；2和5是质因数，所以判断条件：分子对这两个因数取余都不等于0，就是最简。

注意事项:

参考代码:

                                #include<stdio.h>

                                int main()

                                {

                                         for(int i=1;i<40;i++){

                                                 if(i%2!=0 && i%5!=0)

                                                         printf("%d/40,",i);

                                         }

                                         return 0;

                                }
