Data Filters. Programs called data filters are often used to read the information in a data file and then analyze the contents. In many cases, this data filter program is designed to remove any data errors that would cause problems with other programs that read the information from the data file. The next set of programs is designed to perform error checking and data analysis on information in a data file. Generate data files to test all features of the programs.

Write a program that reads a file containing data values computed by an accounting software package. While the file contains only numerical information, the values may contain embedded commas and dollar signs, as in $3,200, and negative values are enclosed in parentheses, as in (200.56). Write a program to generate a new file that contains the values with the commas and dollar signs removed, and with a leading minus sign instead of the parentheses. Do not change the number of values per line in the file.
