To participate in this course, you need to master the basic knowledge of C programming language, equivalent to the content of the CLA program. And it would be best if you prepared a laptop or PC with an internet connection to participate in the course.



The CLP program is designed and divided into 08 main modules with a test preparation time of 16 weeks (corresponding to each module/ 2 weeks):

  • Module 1: You will explore the evolution of C – from past to eternity through the actual contents as obsolete (but still valid) language elements; how do function declarations change over time? Or trigraphs and digraphs.
  • Module 2: You will learn how to handle the variable number of parameters in the C programming language.
  • Module 3: You will in-depth the low-level IO with some basic methods, such as access(), errno, dprintf(), readlink(), etc.
  • Module 4: You will study the memory and strings, including manipulating memory blocks, string manipulation, or Internationalization I18N.
  • Module 5: You will learn the processes and threads in the C consisting of definitions, implementations, history, thread safety, etc.
  • Module 6: You will review the floats and ints once again but the advanced aspects.
  • Module 7: You will find the network sockets with the absolute basics. You will also understand what a socket is? What are a network socket? TCP/IP protocol stack, UDP, or connection and connectionless data transmissions.
  • Module 8: You will learn about Miscellaneous in the C programming language. For example, comparing the const variables vs. volatile variables; goto – why and why not, advantages, disadvantages, limitations, etc.
