ICPC note (7) - stringstream

stringstream可以將string轉為iostream物件，用iostream的基本輸入輸出操作來操作string，可用於連續的字串轉整數

#include<string>
#include<iostream>
#include<sstream>
using namespace std;
int main()
{
  int i;
  string str("87 88 89");
  stringstream ss(str);
  while(ss >> i) cout << i << "+1 = " << i+1 << endl;
}

output

87+1 = 88
88+1 = 89
89+1 = 90
