C Programming Study Materials

C is a procedural, middle-level language with manual memory management that compiles to efficient machine code, widely used in systems programming and embedded systems.

One-dimensional and multi-dimensional arrays, string handling functions, and array operations.

Function definition, call by value/reference, recursion, and library functions.

A pointer in C is a variable that stores the memory address of another variable, enabling direct memory manipulation and efficient passing of data.

Defining structures, accessing members, nested structures, unions, and typedef.

File modes, fopen, fclose, fread, fwrite, fseek, and binary file operations.

malloc, calloc, realloc, free, and memory leak prevention in C.

Singly, doubly, and circular linked lists — insertion, deletion, traversal, and reversal.

Bubble sort, selection sort, insertion sort, merge sort, and quicksort in C.

#define, macros, #include, #ifdef, conditional compilation, and header guards.

AND, OR, XOR, NOT, shift operators, bit masking, and flag manipulation in C.

Common C interview questions, tricky pointer problems, and C vs C++ differences.
