c-codes

Example (explain the problem): one of the major problems faced by safety box user is forget their preset password. As a result, sometimes, user unable to unlock their safety box and need to damage it to get belongings kept inside the safety box. Example solution propose: to replace the conventional safety box with a programmable safety box system. The system enable user to recall back their password (e.g asking several safety questions to before display the user preset password). Your task is to design the complete solution (flowchart, algorithm, c-codes) Your tasks: 1. FIND any engineering problem (eg. a clear figure to show the problem) 2. EXPLAIN the problem based on the selected figure. 3. PROPOSE a solution to solve the problem (flowchart, algorithm, c-codes)
