Introduction to C

Learn how C programs are written, compiled, executed, and organized from the ground up. Build confidence with core programming skills such as storing data, working with text and numbers, receiving input, making decisions, repeating actions, and breaking programs into reusable pieces. Prepare to write simple C programs independently and continue into deeper topics such as pointers, memory management, structs, files, and larger multi-file projects. Certificate upon completion.
