相关疑难解决方法(0)

对不起,如果这是非常noobish,但我是C++的新手.我正在尝试打开一个文件并使用ifstream以下方法阅读:

vector<string> load_f(string file) {
  vector<string> text;

  ifstream ifs(file);
  string buffer, str_line;

  int brackets = 0;
  str_line = "";

  while ( getline(ifs, buffer) ) {
    buffer = Trim( buffer );
    size_t s = buffer.find_first_of("()");

    if (s == string::npos) str_line += "" + buffer;
    else {
      while ( s != string::npos ) {
        str_line += "" + buffer.substr(0, s + 1);
        brackets += (buffer[s] == '(' ? 1 : -1);

        if ( brackets == 0 ) {
          text.push_back( str_line …

我在C++中遇到了一个ofstream错误,这是我的代码

int main () {
  ofstream myfile;
  myfile.open ("example.txt");
  myfile << "Writing this to a file.\n";
  myfile.close();
  return 0;
}

Dev-C++ 10中的错误

C:\ devp\main.cpp聚合`std :: ofstream OutStream'的类型不完整,无法定义
