输入的其实时字符串，对分界点 point(.) 右边的数字进行判断，然后返回point左边的数字字符串
#include <iostream>
#include <string>
#include <cmath>
using namespace std;
void similarNum(string num)
{
for (int i = 0; i < num.length(); i++) {
if (!isalnum(num[i])) { // 为其他字符时
if (num[i + 1] - '5'>= 0) {
cout << stoi(num.substr(0,i)) + 1 << endl;;
} else {
cout << stoi(num.substr(0, i)) << endl;
}
}
}
}
int main()
{
string num;
getline(cin, num);
similarNum(num);
return 0;
}
