Assume that infile has been properly defined to read data from a file and that a file of integers has been properly opened. If you don't know how many integers are in the file, which loop(s) would be appropriate to read in all the values from the file? Variable n has been defined as an int. 1. while(! infile.eof()) 2. for(int x = 0; x < 1000000; x++) 3. while(infile >> n) Answers: A. Both 2 and 3 B. 1, 2, and 3 C. Both 1 and 2 D.

Chapter 4. PC #6. File Letter Counter (page 264) Write a program that asks the user to enter the name of a file, and then asks the user to enter a character. The program should count and display the number of times that the specified character appears in the file. Class name: FileLetterCounter Hints: Hint 1. To read a single character from the keyboard, you need to read a full line and then take the first character in position 0. Hint 2. To count the occurrences of a given characters in a file you need to read the file line-by-line using a while loop, then for each line check all characters in all positions and increment the character counter for each occurrence. This will require to have a for-loop nested inside the while-loop.
