write a c code for the following statement

As a Software Developer, you are tasked by an international construction company that

designs bridges, overhead walkways and gantries, to develop a Linear Thermal

Expansion Calculator program. When a bridge or overhead walkway is constructed, the

Engineer must consider that the material used in the construction will expand or

contract in response to temperature variations. Failure to take the material

expansion$/$contraction into account could potentially lead to severe damage to these

structures, and endanger the safety of the public.

To solve this problem, the engineer needs to determine by how much the length of the

structure will change, and build in a safety factor. The total length of the bridge must be

taken into consideration when determining the expansion length, then allowance

should be made for this movement by including expansion joints $($gaps$)$ over the total

length of the bridge.

Since different construction materials expand $($and contract$)$ at different rates to a

temperature change, a linear expansion coefficient is introduced which has been

determined for various materials. Steel and concrete have the same coefficient

$($CTE$\_$CS$),$ which is $0\mathrm{.}000012$

$,$ and aluminium has a coefficient $($CTE$\_$A$)$ of

$.$ The

coefficient values are constant. The constant identifier names are shown above in

parentheses. $0\mathrm{.}000024$

This multi$-$function program must give the user the opportunity to select the desired

calculation via a menu. This menu will allow the user to select either a single calculation

or generate an expansion table. Once the user has selected their option, the program

will test for a valid user input. If the input is valid, then it will ask the user to enter

certain parameters and the material used before proceeding to the next stage of the

program. Should the user$$s input be invalid, the program will not ask the user to enter

these parameters and will proceed to the next stage. The next stage determines what

further action should be taken based on the user$$s initial selection.
