Inventory Management System

A simple console-based inventory management system built in C#.

Pseudocode

CREATE Product structure (id, name, price, stock)
CREATE InventoryManager with product list
nextId = 1

LOOP forever
    SHOW menu
    choice ← READ integer

    SWITCH choice
        CASE 1:
            READ name, price, stock
            CREATE product with nextId
            ADD product to list
            nextId ← nextId + 1

        CASE 2:
            FOR each product
                DISPLAY id, name, price, stock
            END FOR

        CASE 3:
            READ id, quantity
            IF quantity > 0 AND product exists AND stock >= quantity
                stock ← stock - quantity
            ELSE
                DISPLAY error
            END IF

        CASE 4:
            READ id, quantity
            IF quantity > 0 AND product exists
                stock ← stock + quantity
            ELSE
                DISPLAY error
            END IF

        CASE 5:

            IF product exists
                UPDATE name if provided
                UPDATE price if provided
                UPDATE stock if provided
            END IF

        CASE 0:
            EXIT program
