Question

I convert this code in python to c++:

content = file(filename, "rb").read()

this is the code in c++:

ifstream file;
file.open(filename, fstream::binary);

file.seekg (0, ios::end);
long fileLength = file.tellg();
file.seekg(0, ios_base::beg);

char *content = new char[fileLength];
file.read(content, fileLength);

when I run the python code I get a long string in the content (500 characters~) while the c++ code return only 4 characters.

any suggestion?

thanks

The simplest way to read an entire file is:

std::string content(
    std::istreambuf_iterator<char>(std::ifstream(filename, std::fstream::binary).rdbuf()),
    std::istreambuf_iterator<char>());
