This hands-on self-paced intermediate level C programming course complements our previous C course (or Introduction to C programming language). In our previous course, we covered a comprehensive introduction to the ANSI C language, emphasizing portability and structured design while students were introduced to all major language elements including fundamental data types, flow control, and standard function libraries. as well as other topics like string and character manipulation, dynamic memory allocation, standard I/O, macro definition, the C runtime library, and pointers.

In this course, we continue our journey by covering the Structured programming constructs, the use of aggregate structures, unions and varargs functions. Emphasis is given to the processing of command line arguments and environment variables so students will be able to write flexible, user-friendly programs. The course also includes coverage of portability tips drawn from experienced programmers working in production environments. Comprehensive hands-on exercises are integrated throughout to reinforce learning and develop real competency.
