With this code segment, I must be able to output text file data with names of persons along with int values after performing calculations. The program isolates the names, int values and float values and should output the percentage of each value as a functions of total... example out is...
Total Sales 100,000
Total Expense 25,000.0
Smith John 6.5% 13.2%
Brown Kevin 5.8% 11.3%...and so on
Current the output prints one line of data only. In other words, only the last values on the list is printed onscreen. Please help.
