C Programming Basics

Start with the foundations

A useful starting point is the C Character Set mind map. It groups letters, digits, white spaces and special characters, with examples of character representations. The C Programming Language mind map then introduces variables and types such as char, int and float. Together, they offer a way to move from the characters used in C to the terms used to describe data.

Build your understanding

The Outline of C Programming flashcards cover variables, types and stages of compilation, alongside library headers. Basic definitions offers prompts on topics including enums, loops, functions and arrays. The C Programming note introduces a basic program with a library header and a main function. After reading, use the flashcard prompts to check which terms and definitions you can recall.

Pair a quiz with a map

Programming in C asks about variable names, a loop that executes at least once, and pointers. Try it after exploring the introductory resources. If a question is difficult, return to a relevant map or flashcard deck and look for the concept before trying again. C Language Concept is another map to explore: it brings together data types, operators, loops, arrays, pointers and functions.

Explore the wider unit

C Programming Basics is a section of the C, C++, C# and Other Languages unit in Computing and ICT. The resources on this page offer different ways to study C within that unit: notes for reading, maps for seeing concepts together, flashcards for recall and quizzes for practice. Choose a format that suits your next study session.
