@Qinclude 还有 请检查一下你的prime函数

T13的函数为

int prime(int x)
{
    for(int i=1;i<=100;i++)
        if(i*i*i==x) return i;
}

为什么没人看T8

by tangrunxi @ 2020-05-08 19:40:13

@Qinclude 要换行输出而不是空格

by tangrunxi @ 2020-05-08 19:40:20

@Qinclude T8

by Novice233 @ 2020-05-08 19:40:53

@Qinclude T13的函数的int都换成double

by W_churchill @ 2020-05-08 19:41:37

@tangrunxi 加空格我是为了看哪一点错了，提交的时候没加

by W_churchill @ 2020-05-08 19:42:50

@JR_Stark 改了之后输出nan了？？！！

double(4/3)应该只是把4/3（整除）的结果强制转换为double,建议4.0/3

@Qinclude 8：每行一个数字
