输出末尾不加空格！！！不然格式会一直错误

定义两个容器 一个装入盈数 一个装入完数
#include<iostream>
#include<cstdio>
#include<vector>
using namespace std;
vector<int>v1, v2;
vector<int>::iterator it;
int main() {
int sum, temp;
for (int i = 2; i <= 60; ++i) {//求因子
sum = 0;
for (int j = 1; j <=i/2 ; ++j) {
if (i % j == 0) {
temp = j;
sum += j;
}
}
if (sum == i) {
v1.push_back(i);
}
if (sum > i)
v2.push_back(i);
}
cout << "E:";
for (it = v1.begin(); it != v1.end(); it++) {
cout << " " << *it ;//末尾不加空格！！！不然格式会一直错误
}
cout << endl;
cout << "G:";
for (it = v2.begin(); it != v2.end(); it++) {
cout << " " << *it;//末尾不加空格！！！不然格式会一直错误
}</int></int></vector></cstdio></iostream>

return 0;
