Programming in C Learning Guide: Series Index

Learn to reason about a program before memorizing its syntax. This original Programming in C learning guide begins with no assumed C knowledge. It is the first subject in TechVani's semester-by-semester learning track. The semester label is a study route, not a claim that every institution uses the same syllabus.

How this guide differs from Exam Notes

Each chapter teaches a method from the basics: a precise problem, a manual trace, a complete tested program, explained wrong turns, practice with checked answers, and exam-style questions with answers after each teaching topic. The separate revision notes and lab files remain available; this guide does not replace them.

Start here

Part 1: From a Problem to a C Program. Learn problem contracts, algorithms, manual traces, integer division and remainder, a first C program, build errors and boundary tests. The chapter includes tested code, verified output, Run controls and checked practice.

The learning route

1. From a problem to a C program: explain the problem, trace the steps, build and test.
2. Variables, types and input/output: represent data and read it safely, with limits made explicit.
3. Decisions: translate conditions into branches and check edge cases.
4. Loops: choose a repeated step, show progress and prove when it stops.
5. Functions: separate responsibilities and state the input/output contract.
6. Arrays and strings: track bounds, indexes and string termination.
7. Pointers: distinguish an object, its address and access through that address.
8. Structures and files: group related data and handle storage failures.
9. A small project: combine the methods, tests and error handling.

These are planned stages, not links to chapters that do not yet exist. A stage may need more than one chapter. This page will link only published chapters. Quality, not a word count, decides when a chapter is ready.

Use the guide actively

1. Write down the inputs, expected output and assumptions before reading the answer.
2. Trace the example by hand. Then use its Run control and compare actual and expected output.
3. Attempt the practice before opening the checked answers. Explain why each wrong approach fails.
4. Check your course syllabus for topics or standards beyond this guide. No guide can guarantee a result in every exam.

Other C study routes

C Exam Notes are for compact revision. The C lab file provides additional complete programs. The Online Compiler is available for your own experiments.
