   Programs that interact with users through terminals typically follow a sequential process of execution. Here’s a simplified overview of how such programs are executed:

   1. Initialization: The program initializes variables, sets up necessary data structures, and performs any other initialization tasks.

   2. User Input: The program waits for user input. When the user enters data or commands via the terminal, the program reads this input from the standard input (stdin) stream.

   3. Processing: After receiving user input, the program processes it according to its logic. This may involve computations, data manipulation, decision-making, or other tasks depending on the program’s functionality.

   4. Output: Once the processing is complete, the program generates output to be displayed to the user. This output could be informative messages, results of computations, prompts for further input, or any other relevant information.

   5. Loop: Many interactive programs operate within a loop, continuously waiting for and responding to user input until a specific condition is met (e.g., the user chooses to exit the program).

   6. Termination: Eventually, the program reaches a point where it either completes its task or is terminated by the user. If the program has completed its task, it may perform cleanup actions (e.g., releasing resources, closing files) before terminating.
