C++で文字列を分割する方法

int main(int argc, char **argv) {
  return 0;
}

// 方法1: getlineを使う方法
void method1() {
  string line;
  cin >> line;
  string token;
  stringstream ss(line);
  char delim = ';';
  while (getline(ss, token, delim)) {
    cout << token << endl;
  }
}

// 方法2: boostのsplitを使う方法
void method2() {
  string line;
  cin >> line;
  vector<string> tokens;
  string delim = ";";
  boost::split(tokens, line, boost::is_any_of(delim));
  for (auto token : tokens) {
    cout << token << endl;
  }
}
