C$++$

a$.$ Declare a structure data type with the following fields:

Car id $($integer$),$ Miles Driven $($integer$),$ Gallons Used $($integer$).$

b$.$ Using the data type declared for in $($a$),$ write a C$++$ program that accepts the total number of cars $($assume that there are at most $1000$ cars$)$ and then reads them in$.$

For example

$5$

$25145062$

$363240136$

$44179276$

$522360105$

$68211467$

c$.$ After the data has been entered, the program should print each car's id and the car's $mpg($miles per gallon, as a float$).$ At the end of this, print out also the average mpg for the entire fleet of cars followed by the ids of the cars that have above average $mpg.$
