Arrays : One dimensional arrays: array manipulation; searching, insertion, deletion of an element from an array; finding the largest/smallest element in an array; two dimensional arrays, addition/multiplication of two matrices, transpose of a square matrix; null terminated strings as array of characters, representation sparse matrices. Sorting arrays (Bubble Sort), Searching (Linear, Binary Search), Multiple-Subscripted Arrays.

Functions: top-down approach of problem solving, modular programming and functions, prototype of a function:  parameter list, return type, function call, block structure, Passing arguments to a function: call by reference, call by value, arrays as function arguments.

Storage Classes and Scoping: Automatic, Register, External, Static, Scope of a Variable.

Structures and unions: Structure variables, initialization, structure assignment, nested structure, structures and functions, structures and arrays: arrays of structures, structures containing arrays, unions.  Bit Manipulations and Enumerations: Introduction, Bitwise operators, Bit Fields, Enumerated Constants.

Pointers:  address operators, pointer type declaration, pointer assignment, pointer initialization, pointer arithmetic, functions and pointers, arrays and pointers.

C characters and Strings: Introduction, Fundamentals of Strings and characters, Character and String Handling Library, String conversions and comparison functions.

File processing: Concept of files, Opening and closing a stream, open modes, errno variable. Reading and writing to/from a stream.  Predefined streams: stdin, stdout and stderr. Stream manipulation: fgetc(), fputc(), fgets() and fputs() functions.  Raw input/output: fread() and fwrite() functions. C   Preprocessor, Macros.
