Can the definition and call of functions in C++ be nested?
Article Introduction:Can. C++ allows nested function definitions and calls. External functions can define built-in functions, and internal functions can be called directly within the scope.

However, internal functions cannot directly access local variables of external functions, and the return value type must be consistent with the external function declaration. Internal functions cannot be self-recursive.
