I'm a newbie C++ UNREAL ENGINE

Hi I’m a newbie c++ UE4 and i have basic c++ blueprint and i just started to learn c++ in ue 5 days already my problem is i always forgot how to write any code and i usually review codes in everyday i can just remember a few code.
Should i remember every code ? i want to be good in c++ ue
What should i do ? because i always forgot some code i can just remember a little code
Have anyone experience a problem like this before ? how could you remember code c++ in ue ?

i’m sorry for my english.
Thanks.

You are never going to remember everything and what you will remember comes from repetition. You will eventually get good at remembering where to look up a function instead of remembering it completely.

Repetition is the mother of learning.

Just keep looking it up over and over. One day you will start remembering. Everyone starts this way.
