This is an incomplete program. The goal of the program is to count the number of times 'a', 'e', 'i', 'o', 'u' (and their upper case equivalents) appear in a file.

Complete that program, by defining a?count_vowels?function, that satisfies the following specs:

  • Function count_vowels takes one argument, called in_file, that specifies the name of the input file.
  • If in_file cannot be opened for reading, the function should print on the screen "Error in opening file for reading" and return.
  • Otherwise, the function counts and prints the number of times 'a', 'e', 'i', 'o', 'u' (and their upper case equivalents) appear in a file. Counting should be case-insensitive, so an 'A' should be counted as an 'a' and so on.

IMPORTANT: You are NOT allowed to modify in any way the main function.

For example, for input file: (The CAT is jumping over an airplane. TODAY IS WEDNESDAY. UUUu), the complete program should produce EXACTLY this output:

a: 6 times e: 5 times i: 4 times o: 2 times u: 5 times
