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.

I wrote the code but i can't make the character counter part work.

Required Output

Please enter the file name or type QUIT to exit: Please enter a character: Letter 'o' occurs 4 times in the file 'input.txt'.
