A very intresting method of array initliazation that I have never used before!

new_array_initialization.c

#include <stdio.h>

int main()
{
    int array[10] = {
        [0 ... 9] = -1,
        [8] = 0,
        [0] = 45,
        [1] = 34,
        [5] = 12,
    };

    int i;
    for (i=0; i<10; i++)
    {
        printf("array[%d]=%d\n", i, array[i]);
    }

    return 0;
}


//Compile this program with gcc, run it, and get the result below:
array[0]=45
array[1]=34
array[2]=-1
array[3]=-1
array[4]=-1
array[5]=12
array[6]=-1
array[7]=-1
array[8]=0
array[9]=-1
