The following are sample problems that you should be able to solve under exam conditions (using a blank piece of paper and a pencil). 1. Write a function copyFile that takes two parameters (inFile and outFile) which contain strings representing file names. Your function should copy the contents of the inFile into the outFile in blocks of 50 characters at a time. 2. Write a function filterFile that takes two parameters (inFile and outFile) which contain strings representing file names. Your function should copy the inFile line-by-line into the outFile. Any lines that contain the string "UGA" (anywhere in the line) should be ommitted from the outFile. 3. Write a function that drives your scribbler in a large circle for 30 seconds and samples the center light sensor every second. Write the value (as a string) to a text file named "dataLog.txt", one value per line.
