What does template do in C++?

Templates are powerful features of C++ which allows you to write generic programs. In simple terms, you can create a single function or a class to work with different data types using templates.

What is Template and its types?

Templates are the foundation of generic programming, which involves writing code in a way that is independent of any particular type. A template is a blueprint or formula for creating a generic class or a function.

What is a function template?

Function templates are similar to class templates but define a family of functions. With function templates, you can specify a set of functions that are based on the same code but act on different types or classes.

Is Typedef resolved at compile time?

A typedef is just something to make an alias. The compiler doesn’t care about these internally and it has no impact on the generated code. The final (non-debug) executable will make no reference to either of these things, it’ll all be baked out as machine code. Yes it is resolved at compile time.
