Question

The following code works with GCC’s C compiler, but not with the C++ compiler. Is there a “shortcut” to achieve the same result in C++?

int array[10] = {
    [1] = 1,
    [2] = 2,
    [9] = 9
};

EDIT:
Humm, I found this, clarifies everything.

Answer 1

This form of initialization is only defined in the C99 standard. It does not apply to C++. So, you’ll have to assign your elements one-by-one:

int array[10] = { 0 };
array[1] = 1;
array[2] = 2;
array[9] = 9;
