解析以逗号分隔的std :: string
问题描述：
如果我有一个std :: string包含逗号分隔的数字列表，最简单的方法来解析数字并将它们放在整数数组中？
If I have a std::string containing a comma-separated list of numbers, what's the simplest way to parse out the numbers and put them in an integer array?
我不想把这个概括到解析别的东西。只是一个简单的逗号分隔的整数，如1,1,1,1,2,1,1,1,0字符串。
I don't want to generalise this out into parsing anything else. Just a simple string of comma separated integer numbers such as "1,1,1,1,2,1,1,1,0".

#include <vector>
#include <string>
#include <sstream>
#include <iostream>
int main()
{
std::string str = "1,2,3,4,5,6";
std::vector<int> vect;
std::stringstream ss(str);
int i;
while (ss >> i)
{
vect.push_back(i);
if (ss.peek() == ',')
ss.ignore();
}
for (i=0; i< vect.size(); i++)
std::cout << vect.at(i)<<std::endl;
}
