Description: Template instantiation in C++ refers to the process of creating a concrete instance of a template with specific types. Templates are a powerful feature of the language that allows defining generic functions and classes, facilitating code reuse and the creation of data structures and algorithms that can operate with different data types without the need to duplicate code. When instantiating a template, the compiler generates a specific version of the function or class for the provided data types, allowing for performance optimization and ensuring type safety at compile time. This feature is fundamental in generic programming, as it enables developers to write more flexible and maintainable code. Template instantiation can be explicit, where the programmer specifies the types, or implicit, where the compiler deduces the types from the provided arguments. In summary, template instantiation is a key mechanism in C++ that enhances the versatility and efficiency of the language, allowing programmers to create more robust and adaptable solutions to various problems.
