Computer Engineer

Aspiring software engineers usually major in computer science, computer information systems, software engineering or mathematics. Some students take programming and software engineering classes to supplement a degree in another field, such as accounting, business or finance. You can also pursue relevant certifications offered by software vendors and training institutions.
Software engineers must have strong problem-solving and communication skills and an aptitude for math and science. They should also possess good programming capability; an in-depth knowledge of programming languages, like C+, C#, and Java; an attention to detail; and an ability to handle multiple tasks at once.

A software engineer is a person who applies the principles of software engineering to the design, development, maintenance, testing, and evaluation of the software and systems that make computers or anything containing software work.
You have following options to become a software engineer:
(a) B.Tech CS/ IT
(b) BCA-MCA,
(c) B.Sc-M.Sc CS/IT.
(d) Diploma in Computer Science from a polytechnics
(e) Computer courses
There is only subtle difference between CSE, IT and SE. IT Industry accepts all three to start career as Software Developer. Majority of institutes offer o work as software engineer. B.Tech CSE and it the most accepted degree in IT industry to work as a Software engineer. Let me explain you difference between CS, IT and SE.
Computer science the study of automating algorithmic processes that scale. A computer scientist specializes in the theory of computation and the design of computational systems. B.Tech IT degree has a major focus on computers and technology, it differs from a Computer Science degree in that students are also expected to study management and information science, and there are reduced requirements for mathematics and theory of computation. Software Engineering (SE) deals with building and maintaining software systems. It is more applied than Computer Science, placing greater emphasis on the entire software development process, from idea to final product. It is also more disciplined than Computer Science, applying more systematic practices to help ensure that products are reliable and safe.
