牛客一行輸入多個int型數的方法

---

案例：

#include <iostream>
#include <vector>
#include <string>
#include <sstream>

using namespace std;

int getNum(string &str, vector<int> &inputNum)
{
    istringstream iss(str);
    int num = 0;
    while(iss >> num) {
        inputNum.push_back(num);
    }
    str.clear();
    return 0;
}

int main()
{
    string inputStr;
    vector<int> inputData;
    while (getline(cin,inputStr)) {
        if(getNum(inputStr,inputData)) {
            return 0;
        }
        for (auto i = inputData.begin(); i != inputData.end(); i++) {
            cout << *i << " ";
        }
        cout << endl;
        inputData.clear();
    }

    return 0;
}
