To include a quote character in a string, simply escape that 
character.
Certain characters, such as tab character, newline, and quote 
must be escaped. This is accomplished by preceding the character with a 
backslash. The following example provides the quotes that you requested, as well 
as including a newline character at the end of the line.
fh = 
fopen(...);
...
fputs("\"Date\",\"Time\",\"Open\",\"High\",\"Low\",\"Close\"\n", 
fh);
...
