2. Disadvantages

C++ maintains a high degree of backward compatibility with C, which can sometimes lead to the inclusion of outdated features or practices that may not align with modern programming paradigms, complicating the language further.

While C++11 introduced better support for multithreading, managing concurrency still requires careful attention to detail. Bugs related to thread safety, such as race conditions and deadlocks, can be challenging to diagnose and fix.

Although the C++ Standard Library is robust, it can sometimes lack modern data structures and algorithms compared to more recent languages. Developers may need to implement custom solutions or rely on third-party libraries.

Some features, such as exceptions and RTTI, can introduce performance overhead, making C++ less suitable for scenarios where every millisecond counts.

While C++ supports multithreading, writing concurrent code can be complex and error-prone, requiring careful synchronization to avoid issues like race conditions and deadlocks.

C++ codebases can become outdated and difficult to maintain, especially if they rely heavily on older features or practices that are no longer considered best practices.

C++ has many situations where code can lead to undefined behavior, making it difficult to predict how a program will execute under certain conditions.

Unlike some modern languages, C++ does not have automatic garbage collection, which can lead to increased developer responsibility for resource management.

C++ has limited built-in support for runtime type identification compared to languages with richer reflection capabilities, which can make certain programming tasks more cumbersome.

Different compilers and platforms may implement C++ standards differently, leading to compatibility issues and portability challenges.
