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 : val2evaluates 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
