Lab 7 - May 9

1. Reading from a file

   Download this example file to your account: lab7_input.txt. When you are logged into Helios, you should be able to do the following command to copy the file to your current directory:

   cp /usr/users/mdanfor/public_html/cs221/lab7_input.txt .

   Write a program to read in the data from this file and print it to the screen. Note that the file has an integer followed by a double. Your input statement should look something like this:

   int num;
   double dnum;
   
   fin >> num >> dnum;
   

2. Comparing cout with printf

   Look at this small example of formatting output using printf: lab5_example.cpp. This is the output it produces:

   integer output
   right justify: |         5|
    left justify: |5         |
   
   double output (2 precision)
   right justify: |      5.50|
    left justify: |5.50      |
   
   A small table without borders:
   Name      Integer   Double
   Alice              5      6.20
   Bob                8     13.34
   Carol             12     19.00
   

   Write a program to do the same output using cout.
