Creating a library of string helpers
The string types from the standard library are a general-purpose implementation that lacks many helpful methods, such as changing the case, trimming, splitting, and others that may address different developer needs. Third-party libraries that provide rich sets of string functionalities exist. However, in this recipe, we will look at implementing several simple, yet helpful, methods you may often need in practice. The purpose is rather to see how string methods and standard general algorithms can be used for manipulating strings, but also to have a reference to reusable code that can be used in your applications.
In this recipe, we will implement a small library of string utilities that will provide functions for the following:
- Changing a string into lowercase or uppercase
- Reversing a string
- Trimming white spaces from the beginning and/or the end of the string
- Trimming a specific set of characters from the beginning...
