Editing C syntax (section)

====Compound literals====
It is possible to borrow the initialization methodology to generate compound structure and array literals:

<syntaxhighlight lang=C>
// pointer created from array literal.
int *ptr = (int[]){ 10, 20, 30, 40 };

// pointer to array.
float (*foo)[3] = &(float[]){ 0.5f, 1.f, -0.5f };

struct s pi = (struct s){ 3, 3.1415, "Pi" };
</syntaxhighlight>

Compound literals are often combined with designated initializers to make the declaration more readable:<ref name="bk21st" />

<syntaxhighlight lang=C>pi = (struct s){ .z = "Pi", .x = 3, .y = 3.1415 };</syntaxhighlight>
