c++读取一行整数

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

int main() {
std::vector<int> data;
std::string s;
if (std::getline(std::cin, s)) {
const char *loc = s.data();
int res = 0;
data.push_back(atoi(loc));
loc = strstr(s.data(), " ");
while (loc != NULL) {
data.push_back(atoi(loc + 1));
loc = strstr(loc + 1, " ");
}
}
std::cout << "wangjing" << std::endl;
}
