String Concatenation

Definition

String concatenation is the process of combining two or more strings together into one longer string. It is achieved using the "+" operator in most programming languages.

Analogy

Imagine you have different puzzle pieces with words on them. String concatenation is like putting those puzzle pieces together to form a complete sentence. Each piece contributes its own part, and when combined, they create a meaningful whole.
