Define a sturct called City with components fname $($type string$),$ lname $($type string$),$ id $($type int$),$ and

cost $($type float$)($the cost of a bus ticket to travel to the city$).$

Define a class called Journey with private numberOfCities $($type int$),p$ a pointer of type City,

totalCost $($type float$),$ and the function find Cost$().$ The class has the public member functions set$(),$

$pr{\displaystyle \underset{\phantom{}}{\overset{\phantom{}}{}}}(),$ a parameterized constructor with a default $1$ value as the number of cities, and a destructor.

Implement the member functions, enforcing the principle of least privileged. Define and use three files

$($driver$.$cpp$,$ JourneyImp.cpp$,$ and Journey.h$).$

The following driver produces the given sample of the output:

int main$()$

$\{$

Journey Seeran;

Seeran.print$()$;

Seeran.set$(3)$;

Seeran.print$()$;

return $0$ ;

$\}$

Sample input$/$output:

The journey involves visiting the following $1$ city$|$cities:

$||$First name: Ali $||||$Last name: Omar $||||$ID: $101314||||$ at a travel cost: $10$ Dirham $||$
