Which of the following statements are TRUE? $($Check all that apply$)$

Group of answer choices

C and C$++$ allow subprograms to be called indirectly by defining a pointer to the subprogram. These pointers can be sent as parameters and returned from functions.

Most imperative programming languages do NOT restrict the types that can be returned by their functions

Most imperative programming languages do NOT allow side effects by making it impossible to mutate incoming parameters or global data

Contemporary $$software$-$engineering principles dictate that access by subprogram code to data outside the subprogram should be maximized

When a language implements subprograms as first$-$class objects, they may be passed as parameters or returned from functions.
