In the diagram below, character 2 has 3/4 cover against the attacks of character 1. And character 2 could attempt to hide, with the DM's adjudication.

Cover in D&D is a DM decision, using the parameters in the PLAYER'S HANDBOOK (p. 196).
If you play on a grid, the DUNGEON MASTER'S GUIDE (p. 250–1) provides additional guidance, through text and diagrams. Even then, the DM determines the degree of cover at the game table. #DnD
