Reddit reviews Problem Solving and Program Design in C (8th Edition)

Here's part of a passage that really explains the differences well. I hope it's as helpful for you as it was for me.

This is from Problem Solving and Program Design in C:

Section 2
The College experience: Computer Disciplines and Majors to Choose From

Computer Science

> Computer science as a discipline encompasses a wide range of topics from theoretical and algorithmic foundations to cutting-edge developments. The work computer scientists are trained to do can be arranged into three categories:

> Designing and implementing useful software
> Devising new ways to use computers
> * Developing effective ways to solve computing problems

>A computer science degree consists of courses that include computing theory, programming, and mathematics. These courses ultimately develop the logic and reasoning skills integral to becoming a computer scientist. The math sequence includes calculus I and II (and in many cases, calculus III) as well as discrete mathematics. Some students also study linear algebra and probability and statistics. A computer science degree offers a comprehensive foundation that permits graduates to understand and adapt to new technologies and new ideas. Computer science departments are often found at universities as part of the science, engineering, or mathematics divisions.

> Computer scientists take on challenging programming jobs, supervise other programmers, and advise other programmers on the best approaches to be taken. Computer science researchers are working with scientists from other fields to perform such tasks as using databases to create and organize new knowledge, making robots that will be practical and intelligent aides, and using computers to help decipher the secrets of human DNA. Their theoretical background allows them to determine the best performance possible for new technologies and their study of algorithms helps them to develop creative approaches to new (and old) problems.

Software Engineering

> Software engineering (SE) is the discipline of developing and maintaining large software systems. These systems must behave reliably and efficiently, be affordable, and satisfy all requirements defined for them. SE seeks to integrate the theory of computer science and mathematics with the practical engineering principles developed for physical objects.

> An SE degree program is closely related to the computer science degree
program, and they are usually offered within the same department. In fact, most computer science curricula require one or more software engineering courses. An SE degree can be considered a specialized degree within the confines of the field of computer science.

> SE students learn more about software reliability and maintenance of large systems and focus more on techniques for developing and maintaining software that is engineered to be correct from its inception. Most programs require SE students to participate in group projects for the development of software that will be used in earnest by others. Students assess customer needs, develop usable software, test the product thoroughly, and analyze its usefulness.
Professionals who hold a software engineering degree expect to be involved with the creation and maintenance of large software systems that may be used by many different organizations. Their focus will be on the design principles that make the system viable for many people and through many years.

> Although an SE degree has a recognized description, the term software engineer is merely a job label in the workplace. There is no standard definition for this term when used in a job description, and its meaning can vary widely among employers. An employer may think of a programmer or an IT specialist as a software engineer.
