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.
