At this point, you have seen many examples in which C's display function,
printf, displays strings and numbers. Unfortunately, the report
printed by the most recent version of analyze_trades is ragged
looking:
Food BLD 3.300000 300 990.000000 Trucking GG 2.500000 400 1000.000000 Airline FLY 9.900000 100 989.999939 Airline CH11 10.100000 100 1010.000061 Computers IBM 5.000000 200 1000.000000
You would rather have the report look like this:
Food BLD 3.3 300 990 Trucking GG 2.5 400 1000 Airline FLY 9.9 100 990 Airline CH11 10.1 100 1010 Computers IBM 5.0 200 1000
