Explanation

Class Definition:
- SpeechRecognition class simulates the functionality of speech recognition.
- It contains a private member commands, which is an unordered_map that maps recognized commands (strings) to their responses (also strings).
Constructor:
- Initializes the commands map with a few predefined commands and their corresponding actions.
Member Function:
- recognizeSpeech(const std::string& input) const:
  - Converts the input command to lowercase to ensure case-insensitivity.
  - Searches for the command in the commands map.
  - Prints the corresponding action if found; otherwise, prints “Command not recognized”.
Main Function:
- Creates an instance of SpeechRecognition.
- Prompts the user to input commands.
- Reads user input and uses the recognizeSpeech method to process and respond to the command.
- Allows the user to exit the program by typing “exit”.
