Data structure for BBA(CA) and B.COM (CA) in Pune university

1. Arrays & Strings

• One-dimensional and two-dimensional arrays: definition, declaration, initialization, access

• Algorithms: finding min/max, reversing arrays, identifying odd/even/prime numbers

• Matrix operations: addition, multiplication, transpose, symmetry, triangular matrix 

• String handling: standard library use; custom implementations without built-in functions 

2. Functions

• Function types, declarations, calls, purpose

• Call by value vs call by reference

• Storage classes (auto, static, register, extern) 

3. Pointers & Dynamic Memory

• Pointer basics, arithmetic, indirection operator (& and *)

• Pointer-expression operations

• Dynamic memory allocation: malloc, calloc, realloc, free

• Pointer usage in function calls and return values 

4. Structures & Unions

• Defining structures, accessing members, nested structures, arrays of structures

• Pointers to structures and passing structures to functions

• Differences between structures and unions

• Introduction to unions 

5. Preprocessor Directives & File Handling

(Included in revised NEP‑pattern syllabus)

• Preprocessor: #include, #define (macros, including parameterized/nested macros)

• File handling: streams, types of files (text & binary), operations (fopen, fclose, fgetc, fputc, fseek, fgets, fputs), random access files
