    Code:
    ctemp=(ftemp - 32 /1.8.);
    Which happens first ? (ftemp - 32) or (32 / 1.8) ?

    it must ( 32 / 1.8 ) happen first

    is this acceptable statement ?

    ctemp= ( 32 / 1.8 ) ( ftemp-32 );

    ctemp= ( 32 / 1.8 ) ( ftemp-32 );
    In fact it should be just like this:
    Code:
    ctemp = (ftemp - 32) * 5 / 9;
