Does c++ file ostream or file print function output '\0' to file when output a char array

I want to write some data to a binary file. I output a char array to a file like this

std::ofstream os;
os.open("myfile", std::ios::out | std::ios::binary);
os<<"A";
os.close();

or

char a[]="A";
File* file = fopen ("myfile","wb");
fprintf(file,"%s",a);

And in the end, does the file includes the '\0'?

In other words, the data of the file is 0x41 or 0x4100 in hexadecimal。

No. Strings are printed excluding terminating zero byte.
