Multiple ways of solving the same problem in C++

C++ is a versatile language that offers multiple ways to solve the same problem, a characteristic that can both empower and confuse developers. This flexibility often leads to inconsistencies within a code base, especially when different developers have varying levels of expertise and preferences. In this chapter, we will show a few examples to illustrate how the same problem can be approached in different ways, highlighting the potential benefits and pitfalls of each method. As discussed in the The developer’s personal taste section, developers such as Bob and Alice might approach the same problem using different techniques, leading to a fragmented code base.

Revisiting Bob and Alice’s example

To recap, Bob used modern C++ features such as lambda expressions and auto to process data concisely, while Alice preferred a more explicit and verbose approach. Both methods achieve the same result, but the difference in style...
