COEB$1013$ Programming for Engineers $/$ CSEB$113$ Principles of Programming SEMESTER $12024/2025$

Instructions

Complete the assignment and submit your file$($s$)$ via BRIGHTEN. Pseudocode and flowchart should be submitted as an MS Word or PDF document, and the Python program should be in a ipynb file. Name your file$($s$)$ using the format 'YourID$\_$Shortname$\_$Lab$3\text{'}.$ Please indicate the question number before each section of your code.

Ensure that all variables are named using the format 'variablename$\_xxxx,\text{'}$ where $xxxx$ represents the last four digits of your student ID $($i$.$e$.,$ length$\_1234=15\mathrm{.}61).$

Question $1$

You are designing a temperature monitoring system for an engine. The system needs to continuously monitor the temperature and alert if it exceeds a certain threshold.

Your task is to write a Python program that:

a$)$ Asks the user to input the temperature threshold $($in degrees Celsius$).$

b$)$ Continuously asks the user to input the current temperature.

c$)$ Check if the current temperature exceeds the threshold.

d$)$ Prints an alert message if the temperature exceeds the threshold.

e$)$ Stops monitoring if the user inputs a negative temperature.

You must prepare a pseudocode and a flowchart before you proceed with the programming.

Question $2$

You are tasked with designing a simple traffic light system for a pedestrian crossing. The system should cycle through green, yellow, and red lights and allow pedestrians to cross during the green light.

Write a Python program that:

a$)$ Simulates the traffic light system using a loop.

b$)$ Uses if$-$else statements to change the light colour.

c$)$ Prints the current light colour.

d$)$ Stops the simulation after a certain number of cycles.

You must prepare a pseudocode and a flowchart before you proceed with the programming.
