问题描述
我已经有了要在应用程序中实现的步骤的示例程序。我想将字符串上的int元素分别推入向量。我怎样才能?
I've this sample program of a step that I want to implement on my application. I want to push_back the int elements on the string separately, into a vector. How can I?
#include <iostream>
#include <sstream>
#include <vector>
using namespace std;
int main(){
string line = "1 2 3 4 5"; //includes spaces
stringstream lineStream(line);
vector<int> numbers; // how do I push_back the numbers (separately) here?
// in this example I know the size of my string but in my application I won't
}
推荐答案
int num;
while (lineStream >> num) numbers.push_back(num);
