What is the product for this reaction? CH3CH2CH=CHCH3 + O2 ------> (heat)?

If oxygen is in excess, you will ONLY have carbon dioxide and water (with heat of course).

Thanks. So it's CO2 + H2O
How wouldit change for CH3CH2C triple bond CCH3 + O2 ----->(heat)?

That's the thing, it doesn't change. You just have to balance the equation when you wrote down the substances.
