Pointers, Arrays, and Recursion (Coursera)

Offered by Duke University,
Pointers, Arrays, and Recursion (Coursera)

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.

Syllabus

WEEK 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.

WEEK 2
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.

WEEK 3
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.

WEEK 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.

WEEK 5
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.

Programming Fundamentals (Coursera)

Programming is an increasingly important skill, whether you aspire to a career in software development, or in other fields. This course is the first in the specialization Introduction to Programming in C, but its lessons extend to any language you might want to learn. This is because programming is fundamentally about figuring out how to solve a class of problems and writing the algorithm, a clear set of steps to solve any problem in its class.

Introducción a Java (Coursera)

Me llamo Elisa Viso y una de mis pasiones es la de programar y enseñar a programar. El lenguaje Java es uno de los que más me ha gustado en mis 45 años que llevo programando. Si bien te podrá parecer un poco complicado empezar a programar en Java, una vez que cubras los conceptos básicos verás qué rápido se avanza. Java, como todos los lenguajes de programación bien hechos, te dejan hacer cualquier cosa (algunas de ellas con más trabajo que en otros lenguajes y otras casi directamente de cómo piensas la solución al problema).

Parallel programming (Scala 2 version) (Coursera)

With every smartphone and computer now boasting multiple processors, the use of functional ideas to facilitate parallel programming is becoming increasingly widespread. In this course, you'll learn the fundamentals of parallel programming, from task parallelism to data parallelism. In particular, you'll see how many familiar ideas from functional programming map perfectly to to the data parallel paradigm. We'll start the nuts and bolts how to effectively parallelize familiar collections operations, and we'll build up to parallel collections, a production-ready data parallel collections library available in the Scala standard library.
