Namespaces in C++ are used to organize an excessive number of classes for easier handling of applications. To access classes within a namespace, we need to use namespacename::classname. We can also use the using keyword, so we don’t have to keep using the full name. In C++, the global namespace is the root namespace. global::std … Read more
In C/C++ courses and projects, the application of functions is crucial. Here, we have gathered and organized some commonly used functions in C/C++. We hope you can apply them frequently to gain proficiency. 1. Character Processing Functions This category of functions is used for processing individual characters, including character type testing and case conversion. Header … Read more
The Father of C++ Discusses Five Misconceptions About C++ These five misconceptions have prevailed in C++ for many years: 1. “To understand C++, you must first learn C.” 2. “C++ is an object-oriented language.” 3. “Garbage collection is essential for reliable software.” 4. “To improve efficiency, you must write low-level code.” 5. “C++ is only … Read more
C++ is a high-performance programming language that plays an important role in low-level development and high-performance computing. However, C++ is also a relatively difficult programming language to master; compared to other languages, it is harder to learn and master. To help more students get started with C++, Deep Blue Academy has compiled this content based … Read more
If we create two or more members with the same name but different numbers or types of parameters, this is called C++ overloading. In C++, we can overload: Methods Constructors Index properties This is because these members only have parameters. Types of Overloading in C++: Function Overloading Operator Overloading Function Overloading in C++ Function overloading … Read more
In 2014, the open-source library OpenSSL, which supports secure transport layer protocols, revealed a shocking vulnerability in its TLS/DTLS Heartbeat extension, which contained a buffer overflow vulnerability. This is the infamous Heartbleed vulnerability. This vulnerability allowed attackers to obtain encrypted data and steal the keys used for encryption. Since OpenSSL is one of the foundational … Read more
