void reverse$\_$variables$($float variable$\_$array$[],$ int length$)\{$

$//-------------------------------------------------------$

$//$ This function reverses the order of elements in a $1$D array.

$//$

$//$ Inputs:

$//-$ variable$\_$array: a $1$D array of floating$-$point numbers.

$//$ The array contains the input values to be reversed.

$//-$ length: an integer representing the number of elements in the variable$\_$array.

$//$

$//$ Outputs $($via argument$)$:

$//-$ variable$\_$array: The array is modified in place, so the same variable

$//$ will hold the reversed version of the input array.

$//$

$//$ Functionality:

$//-$ The function modifies the input array in place, reversing the order

$//$ of its elements.

$//$

$//$ Example:

$//$ If variable$\_$array $=\{3\mathrm{.}0,2\mathrm{.}0,1\mathrm{.}0,4\mathrm{.}0,5\mathrm{.}0\},$ the function will reverse it

$//$ in place, resulting in $\{5\mathrm{.}0,4\mathrm{.}0,1\mathrm{.}0,2\mathrm{.}0,3\mathrm{.}0\}.$

$//$
