What does programming with strings allow?

Programming with strings primarily enables the manipulation of text data, which includes operations such as concatenation (joining strings together), slicing (extracting parts of strings), searching for substrings, and modifying string contents through methods like replacement or formatting. This capability is fundamental in many programming scenarios, such as building user interfaces, processing data in text form, and developing applications that require user interaction through text.

While validating inputs is a process that can involve strings, it is not a defining characteristic unique to string manipulation. Combining numerical data typically refers to operations on numbers rather than text. Creating graphical elements is associated more with specific graphics programming or user interface design, rather than string processing. Therefore, the ability to manipulate text data is the essential functionality that programming with strings provides.
