CS-110 teaches students the fundamentals of programming concepts including data types, variables, decision statements, loops, functions, and file handling. By developing simple scripts, students understand how to use common scripting language constructs including lists, literals, and regular expressions to build useful applications. CS-110 serves as a core course requirement for SNHU's Computer Science degree programs and can be taken as an alternative to IT-140 Introduction to Scripting.
Programming fundamentals through hands-on scripting
The course builds foundational programming concepts — variables, decision logic, loops, functions — through actually developing simple scripts, ensuring concepts are learned through direct application rather than abstract description alone.
An entry point with a real alternative pathway
CS-110 explicitly serves as an alternative to IT-140 Introduction to Scripting, reflecting that SNHU offers more than one valid entry point into foundational programming depending on a student's specific program track.
Key topics in CS110
- Data types and variables
- Decision statements and control flow
- Loops and iteration
- Functions and file handling
- Lists, literals, and regular expressions
- Building simple scripted applications
Working on your CS-110 assignments?
Our writers help with CS-110 fundamentals of programming assignments and scripting projects.
Worked example: loops eliminating repetitive code
- Without loops: Writing the same instruction repeatedly for each item in a list
- With loops: A single loop construct processes every item automatically, regardless of list length
- Lesson: CS-110 teaches that foundational constructs like loops aren't just syntax to memorize — they solve genuine, common programming problems efficiently

Frequently asked questions
SNHU structures its curriculum to allow more than one valid path into foundational programming competency depending on a student's specific program or prior background, and since CS-110 and IT-140 both build the same core foundational skills (data types, control flow, functions), satisfying either one demonstrates the same underlying readiness for subsequent coursework. This flexibility reflects that the foundational skill matters more than which specific course number a student's transcript shows.
Foundational concepts like variables, decision logic, and loops are best learned by actually applying them in small, manageable scripts where a student can clearly see cause and effect, rather than being introduced within a complex project where these fundamentals get obscured by other technical complexity. CS-110 starts small deliberately because mastering these basics solidly is what makes more advanced programming coursework (like CS-210's language comparison work) tractable afterward.
