Does == compare string?

== compares the exact values. So it compares if the primitive values are the same, or if the references (addresses) are the same. That’s why == often doesn’t work on Strings; Strings are objects, and doing == on two string variables just compares if the address is same in memory, as others have pointed out. .

What does == mean in Ruby?

The operator == returns true if both objects can be considered the same. For example 1 == 1 * 1 will return true , because the numbers on both sides represent the same value. The expression “A” == “A” also returns true because both strings have the same value.

How do you find not equal to in Ruby?

The != operator, AKA inequality or bang-tilde, is the opposite of ==. It will return true if both objects are not equal and false if they are equal.

How do I check if two strings have the same characters?

Method 2 (Count characters)

  1. Create count arrays of size 256 for both strings. Initialize all values in count arrays as 0.
  2. Iterate through every character of both strings and increment the count of character in the corresponding count arrays.
  3. Compare count arrays. If both count arrays are same, then return true.

How do you compare strings in if statements?
