I'm not an expert, but it seems to me that in the expression "int
a[5]={1, 2, 3, a[2], a[0]+a[1]};" when you say e.g. a[2], you are
referring an uninitialized array. Your code, as far as initialization
goes, would be equivalent to:
int b[5];
int a[5]={1, 2, 3, b[2], b[0]+b[1]};
In this example, it's clear what's wrong. Your code has the same
problem, but slightly obfuscated.
If you try to do the same in Python, you get:
>>> a = [1, 2, 3, a[2], a[0]+a[1]]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'a' is not defined
Which is exactly the same problem you get in C, but exposed better.
