Sometimes, we may also see it formatted as the special character ≠, but we won’t use that character in our pseudocode. The next comparator is the not equal comparator, which is typically written as != in pseudocode. However, it is important to remember that this only works in pseudocode, and will cause issues if used in other languages such as Python. In pseudocode, we use the arrow symbol <- for assignment statements, so we can use the single equals sign for equality. This is because the single equals sign is used in assignment statements in most languages, so we use a double equal as the equality comparator to avoid any confusion between the two. In most other programming languages, the equality comparator is represented by two equals signs = instead of a single one =. The same applies to strings and Boolean values.įor example, we can use the equal comparator to check if two numeric values are equivalent, as shown in this example: Strings and numbers will never be equivalent, even if the string contains text that would convert to the same numeric value.This means that capitalization, punctuation, and other special symbols must all be exactly the same in both strings. When comparing strings, the strings must be exactly identical to be equivalent.This operator can be used between any two values, and it will either result in a value of true if both values are equivalent, or false if they are not. The equal comparator = is used to determine if two values are equivalent.

Let’s review the commonly used comparators in pseudocode. These comparators are a powerful way to build programs that can perform different actions based on data received from the user, as we’ll see later in this lab.

Another powerful feature of pseudocode are the comparator operators, which can be used to create Boolean values by comparing string and number values in an expression.
