Finding # occurrences of a character in a string in Ruby
This link from a question asked previously should help scanning a string in Ruby
scan returns all the occurrences of a string in a string as an array, so
"Melanie is a noob".scan(/a/)
will return
["a","a"]
I was able to solve this by passing a string through scan
as shown in another answer.
For example:
string = 'This is an example'
puts string.count('e')
Outputs:
2
I was also able to pull the occurrences by using scan and passing a sting through instead of regex which varies slightly from another answer but was helpful in order to avoid regex.
string = 'This is an example'
puts string.scan('e')
Outputs:
['e','e']
I explored these methods further in a small video guide I created after I figured it out.
If you just want the number of a's:
puts "Melanie is a noob".count('a') #=> 2
