C++ is an extension of C language. C++ programming language is complex, but strongly preferred in today’s IT sector. You will come across some part of its codebase in generally every system or program. It is the first language developers interested in programming start with. You can learn it with ease as it is purely a concept-based language. The syntax is uncomplicated, so you can easily replicate its writing. Its use is regarded as a safe language due to its valuable features and security. People learn C++ because of several reasons –
This code has a potential problem – an index outside the array bounds. The DWC2State structure defines a glbreg array consisting of 28 elements (comment 1). In the dwc2_glbreg_read function, our array is accessed by index (comment 2). Now note that the function dwc2_glbreg_read is passed the expression (addr – HSOTG_REG(0x000)) >> 2 (comment 3) as an index, which can take a value in the range [0..63]. To make sure of it, pay attention to comments 4 and 5. Perhaps, the range of values from comment 4 has to be fixed.

This story goes back to 2015, when Haiku OS and PVS-Studio static analyzer developers decided to join forces and improve this OS code quality. At first it was more like an experiment, as there was no Linux analyzer at that time and the team had to work only with the compiled executable analyzer file. The entire infrastructure for parsing compiler parameters, running preprocessor, analysis paralleling and so on was taken from the Compiler Monitoring UI utility in C#, which was ported in parts to the Mono platform in order to be run in Linux.
Many beginners and students find C/C++ language hard to master because it requires them to think a lot. There are many language-specific quirks, especially in C++, that give students and programmers a hard time. It also has a steep learning curve and is rarely used in modern application development, which prompts many people to give up learning C/C++. However, even with these challenges, it is important for students to continue learning this programming language. This article highlights reasons why one should keep learning C/C++.
