$1.$ Write a program that creates a singly link list of used automobiles containing nodes that describe the model name $($string$),$ price$($int$)$ and owner$$s name. The program should create a list containing $12$ nodes created by the user. There are only three types of models $($BMW$,$ Cadillac, Toyota$)$ and the prices range from $$7500$ $$20,500.$ The program should allow the user to provide

$$ Print a printout of all cars contained in the list $($model$,$ price, owner$)$ Print$($list$\_$ptr$*)$

$$ Provide a histogram$($global array$)$ of all cars in the list portioned into $$500$ buckets

$$ Find all cars that cost less $$7500-$ find$\_$if$($ list$\_$ptr$*,$ int $)$

$$ Calculate the average price of the cars contained in the list $$ avrg$($list$\_$ptr$*)$

$$ Provide the details for all cars more expensive than the average price

$$ Remove all nodes having a price less than $25\%$ of average price $$ remove$($list$\_$ptr$*,$ int average$)$

$$ Print a printout of all cars contained in the updated list $($model$,$ price, owner$)$
