Study Notes
Assignment Operators
- Assignment operators assign values to variables.
- They perform arithmetic operations.
- Common operators include +, -, *, /.
- Example: 2 + 2 = 4; 20 - 18 = 2.
Comparison Operators
- Comparison operators compare values, returning true or false.
- They check for greater than (>), less than (<), equal to (==), not equal to (!=), and other conditions.
- Critical for equality checks use ==.
- Example: 3 > 2 is true; 2 > 3 is false.
Logical Operators
- Logical operators determine the truth value of conditions.
- AND checks if multiple conditions are true—all must be true.
- OR checks if at least one condition is true.
- NOT reverses the truth value. For instance, !(A > 5) returns false if A is greater than 5.
