Explore the fundamentals of C programming through 15 structured lessons, clear definitions, syntax-highlighted code examples, memory diagrams, and reference tables.
C is the grandfather of operating systems (UNIX, Linux, Windows kernels) and languages like C++, Java, and Python.
Understand computer architecture deeply with true pointers, memory allocation, and hardware register control.
Produces lightweight, compiled machine code with minimal runtime overhead for high-performance systems.
History, key features, Dennis Ritchie at Bell Labs, and program execution flow.
Essential sections of a C program from documentation to main() and sub-functions.
Character sets, identifiers, variable scopes (local vs global), and 32 reserved keywords.
Fixed entities during execution: octal, hexadecimal, real, integer, character, and string.
Data types, memory sizes, format specifiers, and data ranges in C.
8 operator categories, bitwise binary operations, and operator precedence table.
Every concept is illustrated with verified, compilable code examples, real output captures, syntax rules, memory diagrams, and comparison reference tables.
