Read whole ASCII file into C++ std::string
- by Arrieta
Hello,
I need to read a whole file into memory and place it in a C++ std::string.
If I were to read it into a char, the answer would be very simple:
std::ifstream t;
int lenght;
t.open("file.txt", "r"); // open input file
t.seekg(0, std::ios::end); // go to the end
length = t.tellg(); // report location (this is the lenght)
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:
std::ifstream t;
t.open("file.txt", "r");
std::string buffer;
std::string line;
while(t){
std::getline(t, line);
// ... append line to buffer and go on
}
t.close()
any ideas?
