C Programming 2021: Master The Basics!

Install Code::Blocks IDE to write and run C programs, then create a console C project, name and save it, run hello world, and verify the setup.

include standard input output and standard library to use printf. explain the main function, return 0, and that statements end with semicolons; add // and /* */ comments.

Discover how the build process converts C code into object files with a compiler, then links them with headers to create an executable that runs on the computer.

Explore how variables store data in memory using types like int, double, float, char, bool, and string; learn initialization, assignment, casting, and how ASCII values map to characters.

This lecture explains constants in C programming using const and #define, shows how assigning a float to an int truncates to 3, and demonstrates variable addresses and hexadecimal printing.

Learn to use scanf and printf in C to read and print integers, doubles, chars, booleans, and strings with proper format specifiers and line endings.

Explore one- and two-dimensional arrays in C programming, access and initialize elements, understand memory layout, addresses, and the importance of bounds to avoid garbage values.

Learn how C strings work as character arrays with a null terminator, including initialization, memory sizing, and common operations like strcpy, strcat, strlen, strcmp, gets, puts, and ctype checks.

Explore how assignment and arithmetic operators work in C, including division behavior, modulo and type casting; apply relational, logical and not operators, pre/post increments, and sizeof and operator precedence.

Explore decision making in C programming with if-else, nested ifs, and braces; learn switch statements with cases and default, break, and the conditional operator for max, plus simple calculators.

Master basic loop constructs in C by printing array elements with while and for loops, and controlling flow with do-while, break, and continue for input validation and infinite loop handling.

Explore how variable scope works across main and nested blocks, including shadowing, then learn to define and use functions with return values, parameters, and value versus reference passing.
