BU CAS CS 111: Introduction to Computer Science I

Spring 1998

Assignment 6
(due Friday 98.03.27 at 5 p.m. in room MCS 138)

1. [4 points] Exercise 6.15, page 248.
   Test your program 3 times, on the date files:
   • ~cs111/DataFiles/data_file_for_hwk_6_1
   • ~cs111/DataFiles/data_file_for_hwk_6_2
   • ~cs111/DataFiles/data_file_for_hwk_6_3

2. [4 points] Exercise 6.17, page 249.
   Modify the program given in this exercise as follows:
   • Add appropriate statements in "main" in order to read 10 integers and store them in the array "a". (You may therefore omit the initialization of "a" in the declaration of "a".)
   • Change the function "whatIsThis" so that the output of the program is now the minimum value in the array "a" (the function must remain recursive).
   • Test your program on the data file

     ~cs111/DataFiles/data_file_for_hwk_6

3. [4 points] Exercise 6.34, page 257.
   Run your program 5 consecutive times, on 5 different integers read off the keyboard. Make sure to test your program for the case when the search key is not in the array.
