How did the autor put style in the novel "The old man and the sea"?

Hemingway's style–developed when he worked as a newspaper reporter and correspondent early in his career–is simple and compact, with short sentences and paragraphs devoid of verbosity. However, this straightforward style often conveys complex themes. In the The Old Man and the Sea, Hemingway uses the third-person-limited point of view in some sections and third-person omniscient in others. The book won Hemingway a Pulitzer Prize and later helped win him a Nobel Prize.
