Default C variable in WHERE clause problems

Hi all,
can someone show me the correct syntax if using a C variable in a where clause please

where valid='0' is fine but

char zro='0';
where valid=zro doesn't appear to work?

ok solved it, thanks anyway:

sprintf(fnme, "'%s%s", usernm, "'"); // first put quote round it
sprintf(Query, "SELECT * FROM pwdatbla where usernm=%s", fnme);
if (mysql_query(conn, Query)) { //query the database
