int array[] = {1, 2, 3}; /* 3-element array */

Wiki Markupbut it is also possible to use designators to initialize array elements in a noncontiguous fashion. C99, Section 6.7.8, \[ [ISO/IEC 9899:1999|AA. Bibliography#ISO/IEC 9899-1999]\] states

Space can be "allocated" from both ends of an array by using a single designator:

Code Block
int a[MAX] = { 1, 3, 5, 7, 9, [MAX-5] = 8, 6, 4, 2, 0 };

In the above, if MAX is greater than ten, there will be some zero-valued elements in the middle; if it is less than ten, some of the values provided by the first five initializers will be overridden by the second five.
