The revised program still can't read the data from the text file and can't get the highest horsepower and lowest displacement.

When I run the program,$$

the output below:$$

Welcome to the Data Analysis Program!

This program will read from a file and find out which car has the highest horsepower and lowest displacement.

Please enter the input file name: data.txt

Car with the highest horsepower is names with $0$hp$.$

Car with lowest displacement is names with $0$cc$.$

But the result should be read from a text file and get the highest car horsepower and lowest displacement $,$ how can I do that, thanks

$*****$

Welcome to the data analysis program:

This program will read from a file called automobile.csv$,$ gather the data and find out which car has the highest horsepower and lowest displacement.

Please enter the input file name: data.txt

names displacement horsepower

chevrolet chevelle malibu $307130$

buick skylark $350165$

plymouth satellite $318150$

amc rebel sst $304150$

ford torino $302140$

ford galaxie $429198$

Car with highest horsepower is ford galaxie with $198$hp

Car with lowest displacement is ford torino with $302$cc

Thanks for using the data analysis program.
