Double to Const Char*

Question

How can I convert a double into a const char, and then convert it back into a double?

I\'m wanting to convert the double to a string, to write it to a file via fput

Answer 1

Use this funcition :

const char* ConvertDoubleToString(double value){
    std::stringstream ss ;
    ss << value;
    const char* str = ss.str().c_str();
    return str;
}
