A single dimensional array can be declared as int a[10] or int a[] = {1, 2, 3, 4}. It means specifying the number of elements is optional in 1-D array. Given the array above, which statement would change the fifth element to equal 1? void function() { ... }

a[3] = 23;
a[1] = 1;
a[5] = 1;
a[5] = 6;
a[10] = 5
