Võrdlusarvud

Võrdlusarvud, also known as comparison operators, are symbols or keywords used in programming and logic to compare two values and return a Boolean value (true or false) based on the comparison. They are fundamental in conditional statements, loops, and algorithms. Here are some common comparison operators:

Equal to (==): Checks if two values are equal. In many programming languages, a single equals sign (=) is used for assignment, so double equals signs (==) are used for comparison to avoid confusion.

Not equal to (!= or <>): Checks if two values are not equal. The symbol can vary depending on the programming language.

Greater than (>): Checks if the left value is greater than the right value.

Less than (<): Checks if the left value is less than the right value.

Greater than or equal to (>=): Checks if the left value is greater than or equal to the right value.

Less than or equal to (<=): Checks if the left value is less than or equal to the right value.

These operators are essential for making decisions in code, such as determining if a user has entered the correct password or if a loop should continue running. They can be used with various data types, including numbers and strings, but the specific behavior may differ between languages. For example, in some languages, string comparison is case-sensitive, while in others, it is not. It is essential to understand the specific rules and behaviors of comparison operators in the programming language being used.
