Remove an array element and shift the remaining ones

Question

How do I remove an element of an array and shift the remaining elements down. So, if I have an array,

array[]={1,2,3,4,5} 

and want to del

Answer 1

Programming Hub randomly provided a code snippet which in fact does reduce the length of an array

for (i = position_to_remove; i < length_of_array; ++i) {
        inputarray[i] = inputarray[i + 1];
}

Not sure if it's behaviour that was added only later. It does the trick though.
