The incredibly efficient and powerful C language forms the basis for many other languages like C++ and Java. It allows you to interact directly with memory and perform low-level computer operations, enhancing your programming skills and understanding. This makes it an excellent choice for enhancing your programming skills.

This course covers fundamental programming concepts in C, including data types, control flow, functions, input/output, and memory management. It also covers more advanced topics such as compilation, debugging, and parallel programming. The content is comprehensive yet concise, making it accessible to learners at various levels.

By taking this course, you’ll gain a solid understanding of C that will serve as a strong foundation for your programming career. Whether in the early stages of your career or looking to deepen your knowledge, this course will equip you with the skills and insights needed to excel in programming and beyond.

**Profiling** refers to the process of collecting statistics about how a program executes in order to identify bottlenecks in performance and improve program efficiency. 

# How to use the GNU profiler

There is a UNIX utility program called `gprof` that can help us determine which parts of our program are taking most execution time.

The basic steps are:

1.  Compile the program with profiling enabled (using the `-pg` compiler flag).
2.  Execute the program once to generate a profile data file.
3.  Run the `gprof` command to analyze the profile data.

Here is an example program that does some number crunching and that we wish to profile:

Learn about another tool, gprof, available in C and how it helps us find out the program execution time.
