MAKAUT Programming for Problem Solving Organizer | ES-CS-201

1. 01

   Introduction to Programming and Computer Anatomy

   5 points

   • Anatomy and Hardware AssemblyDescribes the computer as a digital electronic machine split into physical hardware (motherboard, CPU, RAM, HDD, I/O devices, secondary storage) and executable software.
   • Computer Software and TranslatorsExplains the binary machine language alongside system software like operating systems, application software, and low/high-level language translators like assemblers, compilers, and interpreters.
   • Problem-Solving ToolsDetails algorithms (sequential, selection, repetition), flowcharts with standardized symbols, decision tables for complex conditions, and informal pseudocode representations.
   • Generations of ComputersSummarizes the evolution across five generations, transitioning from vacuum tubes to transistors, integrated circuits, VLSI microprocessors, and artificial intelligence-based systems.
   • CPU and Storage ArchitectureBreaks down CPU internal components (ALU, Control Unit, Registers, System Buses), primary memory (volatile RAM, non-volatile ROM, Cache), and secondary storage devices (magnetic tape, hard disks, optical CDs).
2. 02

   Arithmetic Expressions and Operator Precedence

   3 points

   • Operator CategoriesClassifies C operators into arithmetic, assignment, relational, logical, bitwise, ternary conditional, increment/decrement, and special operators (sizeof, comma, pointer dereference).
   • Bitwise OperationsDemonstrates bit-level operations including bitwise AND (&), OR (|), XOR (^), left-shift (<<), right-shift (>>), and BCD binary bit manipulation.
   • Precedence and AssociativityOutlines operator evaluation order based on precedence levels and direction of associativity (left-to-right vs. right-to-left).
3. 03

   Conditional Branching and Loop Constructs

   3 points

   • Control StatementsCategorizes C flow control into selection (if-else, switch), iterative (while, for, do-while), and jumping statements (break, continue, goto).
   • Loop ComparisonsEvaluates structural and execution differences between pre-test loops (while, for) and post-test loops (do-while which always executes at least once).
   • Practical Flowcharts and ProgramsProvides step-by-step algorithms and flowcharts for finding largest/smallest numbers, Fibonacci series, grade evaluations, leap year checks, prime checks, and number patterns.
4. 04

   Arrays and Basic Algorithms

   3 points

   • Fundamentals of ArraysCovers contiguous memory allocation for single-dimensional (1D) arrays and multi-dimensional (2D) matrix layouts, including character array string representations terminated by a NULL (\0) character.
   • Searching AlgorithmsContrasts Linear Search ($O(n)$ complexity) with Binary Search ($O(\log n)$ divide-and-conquer strategy on sorted lists).
   • Sorting TechniquesDetails internal and external sorting mechanisms, specifically analyzing Bubble Sort ($O(n^2)$), Selection Sort ($O(n^2)$ with minimal swaps), and Insertion Sort ($O(n)$ best case, $O(n^2)$ worst case).
5. 05

   Functions, Scope, and Preprocessor Directives

   4 points

   • Modular DesignHighlights function prototypes, function definitions, and invocation methods promoting code reusability and readability.
   • Parameter Passing and Variable ScopesCompares Call by Value with Call by Reference, while categorizing identifier visibility across file, function, block, and function prototype scopes.
   • Storage ClassesDetails execution behavior, memory location, initial default value, scope, and lifetime of auto, register, static, and extern variables.
   • C PreprocessorExplains pre-compilation modifications including macro definitions (#define, parameterized, multi-line macros), file inclusion (#include), pragmas (#pragma), and conditional compilation directives (#ifdef, #if, #else, #endif).
6. 06

   Recursion

   3 points

   • Recursive ConceptsDefines recursive self-invoking function calls reliant on base/stopping conditions to avoid infinite stack overflow errors.
   • Recursion Analysis and VariantsDifferentiates direct vs. indirect recursion, tail recursion (optimization by avoiding call stack overhead), and compares recursion against iterative loops.
   • Advanced Recursive AlgorithmsExplains classic recursive implementations including Factorials, Fibonacci numbers, Tower of Hanoi, Eight Queens Puzzle, Quick Sort, Merge Sort, and the fast-growing Ackermann Function.
7. 07

   Structures, Unions, and Bit Fields

   3 points

   • Structure DeclarationsDefines struct types for grouping heterogeneous data variables under a single user-defined record, including self-referential structures containing pointers to their own type.
   • Unions vs. StructuresExplains that structures allocate distinct memory for every member, whereas unions share a single memory space equal to the size of their largest member to conserve memory.
   • Bit Fields and Advanced TypesDemonstrates packing data into explicit bit-widths for space efficiency, as well as type aliasing using typedef.
8. 08

   Pointers and Memory Management

   3 points

   • Pointer FundamentalsExplains pointer initialization, the address-of operator (&), dereferencing (*), double pointers (**ptr), arrays of pointers, and pointer arithmetic rules.
   • Special PointersIdentifies null pointers (pointers assigned to address 0/NULL), generic void pointers (void*), and dangling pointers pointing to deallocated memory.
   • Dynamic Memory AllocationDetails heap memory allocation and deallocation operations using malloc(), calloc(), realloc(), and free().
9. 09

   File Management

   3 points

   • File System StructuresCompares Windows file system path structures with Linux/Unix hierarchical directory structures (/bin, /boot, /dev, /etc, /home, /root, /usr, /var).
   • File I/O Operations in CCovers stream creation using fopen(), mode configurations (reading r, writing w, appending a, and binary b variations), closing streams via fclose(), and standard I/O streams (stdin, stdout, stderr).
   • File Processing FunctionsDemonstrates formatted and unformatted file reads/writes using fgetc(), fputc(), fprintf(), fgets(), fputs(), fread(), and fwrite(), along with random access positioning using fseek(), ftell(), and rewind().
