c++ - 将文件内容复制到字符串

Question

我想将文本文件中的内容复制到string 或*char。如果我可以将文件内容复制到字符串的 array 中(每一行都是该 array 的一个元素)，那就更好了。这是我的代码:

int main() {
   ifstream inFile;
   inFile.open("index.in.txt"); //index.in has in each line a name and at the end there is a "."
   char ab[11];
   int q=0;
   char *a[111];
   if (inFile.is_open()) {
      while (!inFile.eof()) {
         inFile >> ab; //i think i don't understand this line correctly
         a[q]=ab;
         cout<<a[q]<<endl;
         q++;
      }
   }
   else{ 
     cout<<"couldnt read file";
   }
   inFile.close();
   cout<<"\n"<<ab<<endl; //it shoud be "." and it is
   cout<<"\n"<<a[0]<<endl; //it should be "ion" but it gives me "."
   return 0;
}

array 中的所有值都等于最后一行是点

Answer 1

int main() {
   ifstream inFile;
   inFile.open("index.in.txt"); //index.in has in each line a name and at the end there is a "."
   std::vector< std::string > lines;
   std::string line;
   if (inFile.is_open()) {
      while ( getline( inFile, line ) ) {
         lines.push_back( line );
      }
   }
...

现在 lines 是一个字符串 vector ，每个都是来自文件的一行
