I am writing a program that should take the input of the name of a text file and print the number of occurrences of each digit (0 to 9) in the file. The file name is a string, the length of which is between 1 and 60. The file contains between 1 and 1,000 lines, each of which is exactly 60 characters long. The characters in the file may includes digits and punctuation marks. The file does not include spaces, and it also does not include blank lines.

I am having trouble with the output. Every time I run the program nothing happens. The output should look like what is below.
