No, it is the other way around: you can define a structure within a function.
In C++ though, structs are actually classes, so they can have methods.
yes
No. Functions should be defined separately. So you would not define a function within a function. You can define one function, and while defining another function, you can call the first function from its code.
A structure performing a specific function within a cell is called an organelle.
Vestigial structure is used in application to structures that are determined genetically but do not have the ancestral function.
An organelle is a specialized structure within a cell that performs a specific function to help the cell survive and function properly. Examples of organelles include the nucleus, mitochondria, and endoplasmic reticulum.

An organ is a structure that has a definite form and performs a definite function or functions within the body.
That would be an organelle
within its internal structure.

In C++, function bodies are delimited by braces {} to clearly define the scope of the function. This allows the compiler to identify which statements belong to the function, enabling proper organization of code and management of variables' lifetimes. Braces also facilitate the inclusion of multiple statements within a single function, enhancing code readability and structure.
