All Star Code Challenge #18

Description

Create a function that accepts a string and a single character, and returns an integer of the count of occurrences the 2nd argument is found in the first one.

If no occurrences can be found, a count of 0 should be returned.

("Hello", "o")  ==>  1
("Hello", "l")  ==>  2
("", "z")       ==>  0

str_count("Hello", 'o'); // returns 1
str_count("Hello", 'l'); // returns 2
str_count("", 'z'); // returns 0

Notes

• The first argument can be an empty string
• In languages with no distinct character data type, the second argument will be a string of length 1

My Solution

def str_count(word, letter)
  word.count(letter)
end
