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.
