write and read string to binary file C++

Question

Im having problems writing string into a binary file. This is my code:

ofstream outfile(\"myfile.txt\", ofstream::binary);
std::string text = \"Text\";
outfi         


        

Answer 1

the line

outfile.write((char*) &text, sizeof (string));

is not correct

sizeof(string) doesn't return the length of the string, it returns the sizeof the string type in bytes.

also do not cast text to char* using a C cast, you can get hold of the char* by using the appropriate member function text.c_str()

you can simply write

outfile << text;

instead.
