C and C++ Free Courses

These free C programming courses cover core C basics, including variables, data types, input and output operations, operators, arrays, functions, strings, structures, unions, and pointers. They also extend into data structures and algorithms, including stacks, queues, linked lists, heaps, hashing, binary search, trees, sorting, and focused practice programs such as factorial, palindrome, matrix multiplication, and heap sort.

Yes. C for Beginners and Data Structures in C are both marked Beginner level, and the C for Beginners course says it is designed to help you build a strong foundation in coding from scratch. That makes these courses a solid starting point if you want structured basics before moving into data structures or C++ topics.

These free C courses online bring C basics, C practice programs, data structures, algorithms, C++ fundamentals, and OOP topics together in one place. The page lists 17 courses, 600,000+ learners, and a 4.44/5 average rating, making it useful for both first-time learners and learners refreshing core programming concepts.

You build a base in structured programming, problem-solving, memory-related concepts such as pointers, and core data organization methods. The C for Beginners course also says you learn to write efficient system-level code, manage memory manually, develop modular programs, and debug compilation and logic issues.

Yes. Data Structures in C covers arrays, linked lists, stacks, queues, heaps, hashing, binary search, trees, and binary trees, while Algorithms in C adds algorithm-focused study, and Heap Sort Program in C gives sorting practice. The data structures course also includes code demonstrations for major structures such as linked lists, stacks, queues, and binary search trees.
