TOTAL: ?? points

Test 1: Filter Initial Letter from Input File (?? points)

Test 2: Verify the Output File (?? points)

Guidelines

In this program, you will learn to:

• Read from a file
• Write to a file

In this lab, you only need to implement a function filter_initial to complete the following features:

• Takes infile (input file name), outfile (output file name), and letter (the target initial letter to search for)
• Opens the input file and reads the names in the file
• Finds and counts the names with the initial matches letter
• Copies and writes the matched names to the output file (one name per line). Overwrite the output file if exists.
• Handles an exception case when outfile is a NULL pointer. In this case, print the matched names to terminal (stdout) instead.
• Returns the count number of matched names
