Do you want to get a grip on the basic programming concepts from scratch? Do you feel the need to have a better and enhanced understanding of how it all works?  Well, you've come to the right place. This course outlines data types, control flow, functions, input/output, memory, compilation, debugging and other advanced topics in a comprehensive, yet concise manner.

C is where it all begins and where you should also begin to embark on your programming journey. 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 low-level computer operations, thereby enhancing your programming skills and deepening your understanding. This comprehensive and detailed course will introduce you to all the basic and advanced programming concepts of C language. In addition, it also addresses memory, debugging and parallel programming in C.

Sounds awesome? Let's dive in!

Learn C from Scratch

**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 analyse the profile data

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

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