问题标题: 酷町堂：什么鬼(O_o)??

一脸懵逼o((⊙﹏⊙))o

为啥我的代码报错？？？

#include<iostream>
#include<cstdio>
#include<algorithm>
#include<cmath>
#include<iomanip>
#include<string>
int int1(int i) {
	int m=0;
	if (i==1)
		return m;
	else {
		for(int j=2; j<sqrt(i); j++) {
			if (i%j==0)
				m=m+1;
		}
		return m;
	}
}
int main() {
	int m,k=0;
	cin>>m;
	for(int i=1; i<=m/2; i++) {
		if (int1(i)==0&&int1(m-i)==0)
			k=k+1;
	}
	cout<<k;
}

显示

[Error] 'cin' was not declared in this scope
[Error] 'cout' was not declared in this scope

?????
