Ruby - Loops and Iteration

Given a hash scores = { alice: 10, bob: 15, carol: 12 }, how can you use each to print each name and score in the format Name: Score?

Ascores.each { |name, score| puts "#{name.capitalize}: #{score}" }

Bscores.each { |score, name| puts "#{name}: #{score}" }

Cscores.each { |name| puts "#{name}: #{score}" }

Dscores.each { |name, score| puts "#{score.capitalize}: #{name}" }

Step-by-Step Solution

Solution:

Step 1: Understand each on a hash
When using each on a hash, the block receives two variables: key and value.
Step 2: Match variables and format output
The key is the name (symbol), value is the score. Use name.capitalize to print the name nicely.
Final Answer:
scores.each { |name, score| puts "#{name.capitalize}: #{score}" } -> Option A
Quick Check:
Hash each uses key, value pairs [OK]

Quick Trick: Hash each block gets two vars: key and value [OK]
