Array

Question

int A[]={2,3};
int B[]={4,5,6};
int C[];
C=A;
A=B;
B=C;

Does that means C's size is mutable ?

Answer 1

I've tested your code in both C and C++. It is impossible to do

int C[];

As the compiler tries to deduce the size of C but C was not initialized.

It is also impossible to alter or assign an array pointer to another array pointer.

C = A;

If you need an array of mutable size, try vectors.
