Electrical Engineers $($EE$)$ focus on engineering materials and systems to harness the phenomenon of electricity to do useful things with electrical circuits, not just for computation but for many purposes such as electrical power systems.

Computer Scientists $($CS$)$ study the science of computing, dealing with computational algorithms, compilers, interpreters, and making programming languages.

Software Engineers $($SWE$)$ study how to write "good code" especially when working with large code bases.

Computer Engineers are a mixture of EE$,$ CS$,$ and SWE, using some electrical circuit theory, some computer science concepts, and some software engineer skills to build embedded computing systems and computer architectures.
