Possible to initialize an array after the declaration in C?

January 5, 2024 by Tarik

You cannot assign to arrays so basically you cannot do what you propose but in C99 you can do this:

CGFloat *components;
components = (CGFloat [8]) {
    0.0, 0.0, 0.0, 0.0,
    0.0, 0.0, 0.0, 0.15
};

the ( ){ } operator is called the compound literal operator. It is a C99 feature.

Note that in this example components is declared as a pointer and not as an array.
