📌 Assignment Descriptions

Q1: Heap Search Optimization (25 points)

Performs heap search using multithreading and multiprocessing to optimize search time. The task involves implementing a parallelized approach to checking if an element exists in a heap.

Q2: Multi-threaded cp -R Implementation (25 points)

Reimplements the cp -R command using multithreading to improve file copy performance in Linux. This involves reading directories using dirent.h and handling file operations concurrently.

Q3: Multi-process Download Manager (25 points)

Develops a parallel file downloader using multiple processes. It utilizes curl/curl.h to handle multiple file downloads simultaneously, preventing a single slow file from blocking the queue.

Q4: Automated Compilation & Execution (25 points)

Creates a script to automatically compile and execute a C program in a single step, instead of manually running gcc and then executing the output binary.

Q5: Stack Memory Handling (10 bonus points)

Implements a program that takes n numbers from the user and sums them, ensuring that stack memory constraints are handled properly.
