What are the two ways to write a sentence in first conditional?

There are two parts to a conditional sentence. There is an if-clause (also called the conditional-clause) and a main-clause or result-clause. The if-clause contains the condition (the event or situation that must happen first), and the main-clause, which is the result.

Explanation:

The likelihood of the result depends on the type of conditional sentence, which are: zero conditionals (extremely likely) first conditionals (possible) second conditionals (unlikely but still possible)

so whats the question?

honestly, is this even a but since you asked, he's probably at the store trying to get you food.
