I'm not a c/c++ developer by any means,so forgive me if i ask too obvious question, but did you included your variable definition into declare section ( as in cppdemo1.pc ) ?
If i understood it properly,
EXEC SQL BEGIN DECLARE SECTION;

varchar         username[UNAME_LEN];
varchar         password[PWD_LEN];

int howMany;
varchar table_name[SOME_SIZE];
EXEC SQL END DECLARE SECTION; is required for c++ mode.
