C++ Basics: Selection and Iteration

Codio via Coursera


Code and run your first C++ program in minutes without installing anything!

This course is designed for learners with no coding experience, providing a solid foundation of not just C++, but core Computer Science topics that can be transferred to other languages. The modules in this course cover printing, operators, iteration (i.e., loops), and selection (i.e., conditionals).

To allow for a truly hands-on, self-paced learning experience, this course is video-free. Assignments contain short explanations with images and runnable code examples with suggested edits to explore code examples further, building a deeper understanding by doing. You'll benefit from instant feedback from a variety of assessment items along the way, gently progressing from quick understanding checks (multiple choice, fill in the blank, and un-scrambling code blocks) to small, approachable coding exercises that take minutes instead of hours.


  • Basic Skills - Writing your first program!
    • Get started by coding and running your first program in minutes! Learn about the different types of data and how to store it in variables.
  • Operators
    • Use arithmetic operators (+, -, *, /, and %) and boolean operators (and, or, not) to manipulate data stored in variables.
  • Conditionals
    • Program decisions using conditionals so your program can produce different output based on data.
  • Loops
    • Use different types of loops to repeat sections of your program without copying-and-pasting the same lines over-and-over again.
