Study Notes
Assignment Operators
- Assign the value of the right operand to the left operand
-
=
assigns values,+=
adds and assigns,-=
subtracts and assigns,*=
multiplies and assigns,/=
divides and assigns, and%=
divides and stores the remainder - Assigning values to multiple variables simultaneously is valid, e.g.,
x = y = 0
Unary Operators
- Use only one operand
-
+
represents a positive value,-
represents a negative value - Pre-increment/decrement operators (
++
or--
) precede the variable, post-increment/decrement operators follow the variable
Comparison Operators
- Also known as relational operators
-
==
checks for equality,!=
checks for inequality -
>
checks for greater than,<
checks for less than,>=
checks for greater than or equal to, and<=
checks for less than or equal to
Shift Operators
- Used to shift bits to the left or right
-
<<
shifts left,>>
shifts right - Fillings with zeros are added when shifting
Bitwise Operators
- Perform operations bit-by-bit
-
&
(AND) results in 1 if both bits are 1, otherwise 0 -
|
(OR) results in 0 if both bits are 0, otherwise 1 -
^
(XOR) results in 0 if both bits are the same, otherwise 1 -
~
(Inversion) converts 1 to 0 and 0 to 1
Logical Operators
- Combine Boolean expressions
-
&&
(Logical AND) returns true if both operands are non-zero, otherwise false -
||
(Logical OR) returns true if one or both operands are non-zero, otherwise false
Conditional Operator
- Also known as the ternary operator
-
condition ? val1 : val2
evaluates val1 if the condition is true, otherwise val2
Assignment Expression
- Assigns a value to a variable
Relational Expression
- Compares values using relational operators
Logical Expression
- Uses logical operators to combine Boolean expressions
