Lack of knowledge in C++

One of the major contributors to bad code is a lack of knowledge in C++. C++ is a complex and evolving language with a wide range of features, and staying updated with its latest standards requires continuous learning. Developers who are not familiar with modern C++ practices can inadvertently write inefficient or error-prone code. This section explores how gaps in understanding C++ can lead to various issues, using examples to illustrate common pitfalls.

Consider two developers, Bob and Alice. Bob has extensive experience with older versions of C++ but hasn’t kept up with recent updates, while Alice is well versed in modern C++ features.

Using raw pointers and manual memory management

Bob might use raw pointers and manual memory management, a common practice in older C++ code:

void process() {
    int* data = new int[100];
    // ... perform operations on data
    delete[] data...
