Acerca de este curso: The third course in the specialization Introduction to Programming in C introduces the programming constructs pointers, arrays, and recursion. Pointers provide control and flexibility when programming in C by giving you a way to refer to the location of other data. Arrays provide a way to bundle data by guaranteeing sequences of data are grouped together. Finally, recursive functions—functions that call themselves—provide an alternative to iteration that are very useful for implementing certain algorithms.
Para quién es esta clase: This course is for learners who have an interest in learning how to program, for people with no programming experience or for people with some experience who would like to gain solid fundamentals and a deeper understanding of how to program effectively.

SEMANA 1
Pointers
Pointers are one of the most important and powerful aspects of the C language. Pointers are critical to understanding arrays, which let you manipulate sequences of data. They also give a programmer control and flexibility when programming, enabling solutions that are clean and efficient. Some other languages use pointers implicitly—or pointer-like constructs—so understanding their use will make you a better programmer in any language.

Arrays
Arrays are sequences of memory of the same type that are guaranteed to be one after another. This is an incredibly useful data format, enabling you to store many things together under one variable name. In this module, you will learn how to use arrays to solve more complex problems and lay the groundwork for more complex data types.

Uses of Pointers
Now that you have mastered the basics of pointers and arrays, it is time to see some important uses of them. In this module, you will learn about how to manipulate strings and multi-dimensional arrays. You will also learn about function pointers, which allow you to pass "which function to call" as the parameter of another function.

SEMANA 4
Recursion
By now you are familiar with iteration, in which repetition is expressed in terms of loops. Another programming technique to accomplish similar ideas is "recursion" in which a more complex instance of a problem is expressed in terms of solutions to simpler instances of the problem. In this module, you will learn how to read and write recursive code, giving you another powerful option for how to approach programming problems.

Project
Now that you have learned about pointers and arrays, you will build on the code you wrote in Course 2 to build a deck of cards and evaluate a poker hand. In the next course, you will complete the program to calculate poker odds with a Monte Carlo simulation.

End of course project was challenging and fun. Lots of opportunity to learn how to debug memory issues with valgrind.
Wow! I took my first course that was heavy in C in college and I remember it being challenging. Eight years later, I have to say that C is still a challenging topic! I very much enjoying refreshing knowledge that I learned a very long time ago and had forgotten. I'm also pretty pleased with how much better I am at emacs :) I especially liked the clear introduction of how a program is actually organized in memory. Tail recursion explanation was very interesting as well. One thing that I would love to see improved is some of the testing exercises -- it is easy to get stuck and have several days of progress ruined without really learning anything new. This is small but extremely frustrating. Overall I really appreciate this course and think it was immensely helpful for me in my continuing studies. Very well organized and found the pace of the lectures excellent. Very happy and excited, thanks!
