Array declaration and initialization

[Mimic]

When I try to set an array in this way

int num[4];
...
if (foobar == 1) num = { 0, 1, 2, 3 };
else num = { 4, 5, 6, 7 };
...

the compiler raises this error:

error: Assigning to an array from an initializer list

How do I properly set up my array?

Thanks in advance

You can do it like that if you use std::array.

int num[4];
std::array<int, 4> num;
...
if (foobar == 1) num = { 0, 1, 2, 3 };
else num = { 4, 5, 6, 7 };
...
