This course takes a deep dive into the subject of pointers in C programming. It begins by discussing the use of pointers for direct memory access and manipulation in C and then moves on to teach you about changing the memory address contained within a pointer and talks about pointers containing memory addresses of multi-byte variables. It then explains how pointers have memory addresses as well, introduces the char pointer and explains why you need to learn pointers in C programming.
The course then moves on to introduce the important concept of constants and string literals in C programming before reviewing and clarifying some of the information you have learned. It then takes a deeper dive into both strings and constants in C, and explains a new way to visualize random access memory (RAM). The course also discusses how to use a pointer to directly manipulate data in memory in C programming.
Finally, the course teaches you about the character string as an array of characters in C programming. Whether you are aiming towards a career in computer programming or simply want to build your knowledge of one of the most popular programming languages, this course teaches some of the foundational concepts of C programming. So start this course today to learn more about programming in C.Start Course Now
