Project #4
Due by 11:59pm on Thursday, April 17, 2008
You will wr ite t wo p rograms for this project. The first program “removedups” eliminates double entries
in an array of integers. The second program “checker” corrects simple syntax errors in English text .
1. Removedups. Write a program that accepts a sequence of integers (some of which may repeat) as input
into an array. Write a function tha t processes the array so that any duplicate values are eliminated. Write
an output function that prin ts out the values of the array and the su m of the values. You can assume that
there are no more than 20 in tegers in the input. B ut there may be less. Zero signifies the end of input. The
zero should NOT be printed.
For example, when the following input is provided to your program:
5 6 22 5 22 7 6 0
your program shou ld print:
The sum of 5 6 22 7 is 40
• You mus t use an array to store the numbers that are input.
• Develop your program wi th the functions in a separate file called dupfuncs.cpp and the main in a
file called: removedups.cpp
• EXTRA-CREDIT OP TION: for 10% extra credit you may p rompt t he user for a file name from wh ich
to receive the integer input, but your program must also offer the interactive input option as specified
in the original description.

2. Checker. Write a program that reads in English text. The program should output the text with spacing
corrected and with letters corrected for capitalization. In particular, in the output text all strings of two or
more blank spaces should be compressed to a single blank. Each sentence (a letter starting the text and
following a dperiod) shou ld start with an uppercase letter. There should be a space after a comma or a
period. No other formatting is required.
For example, the input:
the Answer to life,the Univ erse, and everything is 42 . that is all .
Do , or do not . there IS No 'try' .
Should produce the following output:
The answer to life, the un iverse, and ev erything is 4 2. That is a ll.
Do, or do not. There is no 'try'.
• An empty line signifies the end of inpu t. Th is emp ty l ine should NO T be output .
• You mus t use a C+ + s tring to s tore a line of input.
• Develop your program using appropriate functional decomposition, place the functions in a file called
checkerfuncs.cpp and the main i n a file called: checker.cpp
• EXTRA-CREDIT OP TION: for 10% extra credit you may p rompt t he user for a file name from wh ich
to read in the sentences (lines), but your program must also offer the interactive input option as
specified in the original description.
