Please staple the assignment together. At the top of the first page print, in this order: your first name, your last name, CIS33A, and the assignment letter. Print the problem number at the beginning of each problem. Assignments are due at the beginning of class, and will be marked down if turned in later.
Authorship note: These assignments have been adapted from assignments given by Clare Nguyen, who adapted them from the work of Behrouz Forouzan.
Programming Problems are to be done on the computer. Hand in your your source code and program output.
Write a Perl program which opens and reads input from a text file. In this file, each line of text may have multiple occurrences of digit strings.
Your program will extract the digit strings from each line. Repeated occurrences of the same digit string in the same line will be ignored.Your program will print the unique numbers within each line. Your program will also print the total of these numbers.
Using an input file containing:
99 percent of the time, 99 out of 100 people will not pick the number 1 as the first choice. A stitch in time saves 9 but only if you have exactly 9. 76 trombones were in 4 marching bands in the big parade of '76 and 76 people attended.
The first line contains the unique numbers: 99 100 1
The second line contains the unique numbers: 9
The third line contains the unique numbers: 76 4
The total is: 289
Your output should look like this:
99 + 100 + 1 + 9 + 76 + 4 = 289
Hint: use the best data structure to make unique entries.
Write a program that allows a user to enter lines of text from the keyboard, which look like this:
San Diego 85
Your script will process input lines as follows:
Using the following input:
NeW YoRk CITy 44 San JOSE 66 denver 66 44 St. Louis 55 Los Angeles x5 Cupertino Anchorage -2 Death VALLEY 112 Quit
The Denver, St. Louis, Los Angeles, Cupertino, and Death Valley lines should be rejected.
The output should look like this:
NEW YORK CITY 44 SAN JOSE 66 ANCHORAGE -2 Cities: 3 Average Temperature: 36
