Which of the following cannot be a structure member?Question 19Select one:Another structureFunctionArrayNone of the mentioned

To answer the question of which option cannot be a structure member in the context of programming (specifically, in languages like C or C++), let's analyze the choices provided:

1. Another structure: This can indeed be a member of a structure, allowing for nested structures.
2. Function: Functions themselves can’t be members of a structure, but function pointers can. However, since the option refers to "function" and not "function pointer," it is usually considered incorrect to call a direct function a member of a structure.
3. Array: Arrays can be structure members, and they are commonly used in structure definitions.
4. None of the mentioned: This option suggests that all prior options can be structure members, which is not true in the case of “Function.”

Conclusion

Given the analysis, the option that cannot be a structure member is Function.
