C$++,$ data analysis program,

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

$($ automobile.csv data:

names displacement horsepower

chevrolet chevelle malibu $307130$

buick skylark $320350165$

plymouth satellite $318150$

amc rebel sst $304150$

ford torino $302140$

ford galaxie $500429198$

I wrote a part of the program, but it doesn't work properly. my program is as follows:
