✐ Examples

1 Get Character at Index 4 in "Hello World" String

In this example,

  1. We create a string named str with a value of "Hello World".
  2. We then access the character at index 4 using array-like indexing or the [] operator on the string str.
  3. Finally, we use puts to print the character at index 4.

Ruby Program

str = "Hello World"
char_at_index_4 = str[4]
puts "Character at index 4: #{char_at_index_4}"

Output

Character at index 4: o

2 Get Character at Index 1 in "Ruby" String

  3. Finally, we use puts to print the character at index 1.

Ruby Program

str = "Ruby"

puts "Character at index 1: #{char_at_index_1}"
