How to create a new string which is n copies of a given string in ruby

How can I create a new string which is n copies of a given string in ruby? I tried these but none of them worked -

n = 5
string = "This is a string"
my_string = ""
my_string =  n.times do
  my_string << string
end

puts my_string

Thanks in advance

I don't know if this is exactly what you are looking for. But you can use the string * integer method.

n = 5
string = "This is a string"
my_string = string * n

puts my_string

You can use the String#* method. For example:

str = "This is a string.\n"
str * 5
#=> "This is a string.\nThis is a string.\nThis is a string.\nThis is a string.\nThis is a string.\n"

Similarly, puts str * 5 will return nil, but print the output with newlines to standard output. For example:

This is a string.
This is a string.
This is a string.
This is a string.
This is a string.

Use the String#* operator:

n = 5
string = "This is a string"
my_string = string * n

This is a stringThis is a stringThis is a stringThis is a stringThis is a string

You can create an array with n string elements, and then join each of them:

Array.new(n, string).join
# "This is a stringThis is a stringThis is a stringThis is a stringThis is a string"

You can also use the * method which returns a new String containing integer copies of self:

string * n
# "This is a stringThis is a stringThis is a stringThis is a stringThis is a string"
