Võrdlusmärgid

Võrdlusmärgid, also known as comparison operators, are symbols used in programming and logic to compare two values. They evaluate the relationship between operands and return a boolean value: true or false. The most common comparison operators include equal to, not equal to, greater than, less than, greater than or equal to, and less than or equal to.

The equal to operator, typically represented by ==, checks if two values are identical. For instance, 5 == 5 would evaluate to true, while 5 == 6 would be false. The not equal to operator, denoted by !=, performs the opposite check, returning true if the values are different and false if they are the same. 5 != 6 is true, whereas 5 != 5 is false.

The greater than operator, >, determines if the left operand is larger than the right operand. 10 > 5 is true. Conversely, the less than operator, <, checks if the left operand is smaller than the right operand. 5 < 10 is true.

The greater than or equal to operator, >=, returns true if the left operand is greater than or equal to the right operand. 10 >= 5 and 10 >= 10 both evaluate to true. Similarly, the less than or equal to operator, <=, returns true if the left operand is less than or equal to the right operand. 5 <= 10 and 5 <= 5 are both true.

These operators are fundamental in controlling program flow, forming conditions for loops and conditional statements like if-else structures, and in data manipulation where specific criteria need to be met.
