C Learning Path.

Understand source code, GCC compilers, compilation stages, and the systems C mindset.

Master main(), variables, static types, printf(), scanf(), format specifiers, and casting.

Branching (if/else, switch) and loops (for, while, do-while, break, continue).

Prototypes, stack frames, call-by-value, variable scope, and call stack recursion.

Contiguous memory indexing, 1D/2D arrays, char[] buffers, and null terminator '\0'.

Address-of operator (&), dereference operator (*), pointer arithmetic, and call-by-reference.

Stack vs Heap, malloc(), calloc(), realloc(), free(), and preventing memory leaks.

struct, typedef, arrow operator (->), nested records, and memory alignment padding.

File pointers (FILE*), fopen, fclose, fprintf, fscanf, and stream processing.

Searching, bubble sorting, pattern generation, and matrix algorithms in C.

Valgrind debugging mindset, segfault analysis, buffer overflows, and memory safety.
