C | Arrays | Question 14

Which of the following is true about arrays in C.
(A) For every type T, there can be an array of T.
(B) For every type T except void and function type, there can be an array of T.
(C) When an array is passed to a function, C compiler creates a copy of array.
(D) 2D arrays are stored in column major form


Answer: (B)

Explanation: In C, we cannot have an array of void type and function types.

For example, below program throws compiler error

int main()
{
    void arr[100];
}

But we can have array of void pointers and function pointers. The below program works fine.

int main()
{
    void *arr[100];
}

See examples of function pointers for details of array function pointers.
