In this lecture we learn Array Operations Technique and Code in C++ like finding the maximum number, the second maximum number, and performing searches in an array. These operations form the bedrock of many algorithms and data-structure tasks. We will…
Understand Composition and Aggregation in Object-Oriented Programming. Learn the “has-a” relationship, difference between inheritance and composition, and explore real-world examples like Car and Engine in C++ and Java. Introduction So far, we’ve learned about Inheritance (the is-a relationship) where a…
IoT application protocols like HTTP, MQTT, and CoAP, including message formats, QoS levels, and a hands-on MQTT publish-subscribe lab using Node-RED. Introduction The Internet of Things (IoT) depends on communication protocols that enable devices to send, receive, and process data…
Learn about Exception Handling in Object-Oriented Programming. Understand the difference between errors and exceptions, master try-catch blocks, and explore how to create custom exception classes in C++ and Java with examples. Introduction In programming, errors are unavoidable but how we…
Present rapid warming shows Earth is heating faster than ever recorded. Learn how scientists project future climate change and why uncertainty in climate projections matters for understanding our planet’s future. Introduction Earth’s climate is warming at an unprecedented pace. Over…
IoT networking fundamentals with IPv6, 6LoWPAN, Wi-Fi, LoRaWAN, and BLE protocols. Includes an ESP32 Wi-Fi connection lab for practical understanding. Introduction Networking is what connects the “things” in the Internet of Things (IoT). Without communication, sensors can’t send data, and…
