What is a concatenation in programming?

Concatenation in programming refers specifically to the operation of joining two or more strings together to form a single string. This operation is fundamentally important in many programming languages, as it allows developers to build dynamic text outputs, combine user inputs, or construct complex data strings.

For instance, if you have a string containing a user’s first name and another containing their last name, concatenating these strings allows you to create a full name. The process typically utilizes operators or functions predefined in the programming language to accomplish this task effectively.

Understanding concatenation is crucial because it provides a way to manipulate and interact with string data, which is an essential part of programming tasks such as formatting output or creating complex messages.
