I really can't find where the Standard forbids the following!

int a[2] = { 1, 2 };
int b[2];
b = a;

I thought somewhere the Standard says that lvalue expressions of array
type
are nonmodifiable, but I can't find it!

Any insights?

Use the STL as its there for reason.

#include <vector>

std::vector<int> a, b;
a[1] = 1;
a[2] = 2;

b = a;

will work as desired

Apart that you missed the point, you posted non working code - that
happens to me too, but somebody always has to point it out, sorry.

Needs push_back() instead of subscript operators or else a properly
sized "a" before assigning the elements as you did. And main() to wrap
the code ;-)
