Task Manager

Overview

Task Manager is a C++ program that displays and manages processes running on your system. The program interacts with the tasklist command to retrieve and parse details about active processes, including:

• Image Name
• PID (Process ID)
• Session Name
• Session ID
• Memory Usage

Features

1. Display all running processes.
2. Sort processes by:
   • Image Name
   • PID
   • Session Number
   • Memory Usage
3. Filter processes by session name (e.g., Console or Services).
4. Exit the program gracefully.

How It Works

The program uses the tasklist command to generate a CSV file of processes, parses the file to extract process details, and provides sorting and filtering options to the user.

---

Usage Instructions

1. Run the Program

Compile the program and execute it:

g++ -o TaskManager TaskManager.cpp
./TaskManager

2. Program Menu

When the program runs, you'll see the following menu:

Choose:
 1) Display Processes.
 2) Display Sorted Processes by Image Name.
 3) Display Sorted Processes by PID.
 4) Display Sorted Processes by Session Number.
 5) Display Sorted Processes by Memory Usage.
 6) Display Filtered Processes by Session Name.
 7) Exit Program.

Enter your choice to interact with the program:

• Option 1: Display all processes.
• Option 2-5: View sorted processes.
• Option 6: Filter processes by session name (Console or Services).
• Option 7: Exit the program.

Example Output

Here’s an example of the program’s output when displaying processes:

                              The Processes are:

Image Name                    PID Session Name        Session#    Mem Usage

Code Details

Core Classes and Functions

• TaskManager Class: Manages all process-related operations.

  • displayProcess(): Displays all processes.
  • sortedByImageName(): Sorts by image name alphabetically.
  • sortedByPID(): Sorts by Process ID.
  • sortedBySessionNumber(): Sorts by session number.
  • sortedByMemoryUsage(): Sorts by memory usage (numerical).
  • filterSessionName(): Filters processes by session name.

• Helper Functions:

  • convertMemoryUsage(): Converts memory usage strings to integers for sorting.
  • splitWords(): Parses CSV file lines to extract process details.

Dependencies

The program uses:

• <bits/stdc++.h> for standard C++ libraries.
• tasklist command (Windows).

---

Requirements

• Operating System: Windows
• Compiler: g++
• The program relies on the tasklist command, so ensure it's available in your environment.
