Section 5 : Lab 01 - People Database Stats

Todo 1

Given a file with Comma-Separated-Values represensenting information about individuals, write a Go program that does the following:

1. Read the records form the data file. Data file name is passed as a program argument to the program.
   • Hint: Use os.Args
   • TIP: Examine a few lines of the data file to see what the records look like.
2. For each line read from the file, initialize a Person struct object.
   • TIP: Write a function which takes a CSV string and returns a Person object.
   • TIP: You will need to use the packages 'strings' and 'strconv'.
   • HINT: If using the 'input.FileReader' object, be sure to check for io.EOF when reading records and handle it occordingly.
3. Compute the following stats by gender:
   1. total number of records
   2. min salary
   3. max slary
   4. average salary

Requriements

1. You must use a Struct type to represent a record from the file.
   • HINT: Your program may be eaiser and cleaner if you user an additional struct for stats data. See the solution for one example.
2. Use more than one files for readablity.
   • TIP: Consider breaking your program into packages.
   • TIP: If you are writing a package:
     • use go install to install it
     • use go doc in the pacakge dir to check import and usage
