How to use don't and won't

[Ragha_ts]

Hi,

I always getting confused with Don't and Won't. Where exactly we have to use Don't and Won't. I think most of the time I am using Don't in place of Won't and vice versa.

Ex: They don't come
They Won't come.

I really thankful if anybody can explain this with examples how Don't and Won't are different and the situation where to use.

Thanks.

Don't means "Do not". Won't means "Will not".
You need to understand the differences between 'do' and 'will' first - this is quite basic.
