Scope Bruce Bolden Due: Week of October 11, 2016 CS 120 Lab 6: Scope Scope rules determine where a variable is available for use in a program and...

The following program is an example of very poorly used scope rules. The mixture of local variables, global variables, pass-by-reference, pass-by-value, and repeated variable names makes it difficult to predict what will be printed. Enter the program, without line numbers, then compile and run the program. Save the output to a file using the script command. Edit the output file, by adding text that explains for each line of the output where the variable was declared and where it's value was assigned, using the line numbers to help. For example, part of the explanation of the first line of output would be: x was declared on line 9 and it was assigned the value 0 on line 9". Print and turn in your annotated output.
