C++ 获取一整行(一行)字符串并转换为数字

代码很简单，主要是自己总是忘记，记录一下：

#include <iostream>
#include <cstdlib>
#include <cstring>

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

using namespace std;

void print_int_arr(vector<int> nums)
{
    cout << "nums: ";
    for (int num : nums)
    {
        cout << num << "  ";
    }

    cout << endl;
}

int main()
{
    string str1, str2;

    // 获取一整行字符串
    getline(cin, str1);
    getline(cin, str2);

    vector<int> num1, num2;

    cout << "demo: " << endl;
    cout << str1 << endl;
    cout << str2 << endl;

    int num;

    // 转换数字
    stringstream ss1(str1);
    while (ss1 >> num)
    {
        num1.emplace_back(num);
    }

    stringstream ss2(str2);
    while (ss2 >> num)
    {
        num2.emplace_back(num);
    }

    print_int_arr(num1);
    print_int_arr(num2);

    return 0;
}

结果如下：

[chen@localhost]$ ./a.out 
11 22 33 1 0 21
23
demo: 
11 22 33 1 0 21
23
nums: 11  22  33  1  0  21  
nums: 23
