To merge to arrays ( Note the question has no mention of
sorting the array elements, hence the program below just
merges two arrays)

int array1[5] = {1,2,3,4,5};
int array2[7] = {6,7,8,9,10,11,12};
int i;
int merged[(sizeof(array1)+ sizeof(array2))/sizeof(int)];
memcpy( merged, array1, sizeof(array1));
memcpy( (merged+5), array2, sizeof(array2));

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