字符串转化并累加

    一行字符类型的数字，每个数字以空格隔开，将它们转化为数字后累加求和

 

#include <iostream>
#include <string>
#include <sstream>
using namespace std;

int main() {
    string str;
    while (getline(cin, str)) {
        int sum = 0, num = 0;
        stringstream ssio(str);
        while (ssio >> num)
            sum += num;
        cout << sum << endl;
    }

    return 0;
}
