Uniform continuity and bounded sequence

Problem

If the sequence ${f_n}\subset C[a,b]$ is uniformly continuous, it is bounded.

If the sequence ${f_n}\subset C[a,b]$ is bounded, it is uniformly continuous.

Maybe someone can give me some hints for this? Thanks so much in advance!

1) Take a sequence of constant functions that diverge to infinity

2) Take a sequence $f_n (t) =[(b-t)(b-a)^{-1} ]^n $
