Assignment 5
(due Friday 98.03.20 at 5 p.m. in room MCS 138)

1. [4 points] Exercise 5.35, page 197.
   We want you to execute your program 3 times consecutively before handing it in.

2. [4 points] Exercise 5.42, page 200.
   Your program must satisfy the following requirements:
   • It must include a main function, which in turn calls the gcd function.
   • It should read a pair of positive integers from a date file (not from the keyboard).
   • You should test your program on the input file "data_file_for_hwk_5" in directory ~cs111/DataFiles, by executing the command:

     a.out < ~cs111/DataFiles/data_file_for_hwk_5

     at the Unix prompt. This date file contains 10 integers, all on the same line, where each two consecutive integers must be read together.

3. [4 points] Exercise 5.47, page 200.
   

4. [4 points] Exercise 5.48, page 201.
   Modify the program as stated in the exercise. Then run it so that it reads a pair of positive integers from a date file (not from the keyboard). Test your program on the input file "data_file_for_hwk_5" in directory ~cs111/DataFiles, by executing the command:

   a.out < ~cs111/DataFiles/data_file_for_hwk_5

   at the Unix prompt. This date file contains 10 integers, all on the same line, where each two consecutive integers must be read together.
