I need to load an entire file into memory and store it in a C++ std::string.
If I read it into a char[,] the answer is straightforward:
t.open("file.txt"); // open input file
t.seekg(0, std::ios::end); // go to the end
length = t.tellg(); // report location (this is the length)
t.seekg(0, std::ios::beg); // go back to the beginning
buffer = new char[length]; // allocate memory for a buffer of appropriate dimension
t.read(buffer, length); // read the whole file into the buffer
t.close(); // close file handle
// ... Do stuff with buffer here ...
Now, I want to do the exact same thing, but using a std::string instead of a char. I want to avoid loops, i.e. I don't want to:
// ... Append line to buffer and go on
