Compound literal having length of initializer

less than array size specified

int *p = (int [10]){1, 2, 3};

rest of the elements of compound literal will be initialized to 0 implicitly.

Read-only compound literal

Note that a compound literal is an lvalue and therefore it's elements can be modifiable. A read-
only compound literal can be specified using const qualifier as (const int[]){1,2}.

Compound literal containing arbitrary

expressions

Inside a function, a compound literal, as for any initialization since C99, can have arbitrary
expressions.

void foo()
{
int *p;
int i = 2; j = 5;
/*...*/
p = (int [2]){ i+j, i*j };
/*...*/
}
