Aim lock c++

Hey, could someone give me a few pointers on how I would go about locking the cross hair on to an entity in csgo using c++?

I have an array of all the enemies already and have made a trigger bot and radar hack, but don't know how to get the view angle needed and set the view angle to keep locked.

If anyone wants to help, Thanks in advance !!

look at T-T's source code
