General Programming → Order Of Operations

Operations level 1

Operator Syntax Explanation
++ x++ a unary operator that increases the value of "x" by one
-- x-- A unary operator that decreases the value of "x" by one

Operations Level 2

Operator Syntax Explanation
++ ++x a unary operator that increases the value of "x" by one
-- --x A unary operator that decreases the value of "x" by one
+ +x A unary operator that does ????????
- -x A unary operator that does ????????
!  !x A logical operator that returns a boolean value that is the opposite of "x" (If "x" is true, then "!x" returns false)

Operations Level 3

Operator Syntax Explanation
/ a / b An operator that returns the value of "a divided by b"
* a * b An operator that returns the value of "a multiplied by b"
% a % b An operator that returns the value of "the remainder of a divided by b"

Operations Level 4

Operator Syntax Explanation
+ a + b An operator that returns the value of "a plus b"
- a - b An operator that returns the value of "a minus b"

Operations Level 5

Operator Syntax Explanation
/ a / b An operator that returns the value of "a divided by b"
* a * b An operator that returns the value of "a multiplied by b"
% a % b An operator that returns the value of "the remainder of a divided by b"

Operations Level 6

Operator Syntax Explanation
>> a >> b A bitwise shift to the right ?????????
<< a << b A bitwise shift to the left ??????????

Operations Level 7

Also known as "boolean operators" for returning boolean values

Operator Syntax Explanation
< a < b A logical statement that returns "true" if "a" is less than "b"
* a <= b A logical statement that returns "true" if "a" is less than or equal to "b"
> a > b A logical statement that returns "true" if "a" is greater than "b"
>= a >= b A logical statement that returns "true" if "a" is greater than or equal to "b"

Operations Level 8

Also known as "boolean operators" for returning boolean values

Operator Syntax Explanation
== a == b A logical statement that returns "true" if "a" is equal to "b"
!= a != b A logical statement that returns "true" if "a" NOT equal to "b"

Operations Level 9

Operator Syntax Explanation
& a & b A bitwise operator AND ????????

Operations Level 10

Operator Syntax Explanation
^ a ^ b A bitwise operator ExclusiveOR ????????

Operations Level 11

Operator Syntax Explanation
| a | b A bitwise operator OR ????????

Operations Level 12

Operator Syntax Explanation
&& a && b Returns "true" if both "a" and "b" are also true

Operations Level 13

Operator Syntax Explanation
|| a || b Returns "true" if either "a" or "b" is true

Operations Level 14

Operator Syntax Explanation
?: a ? b : c Ternary operations: see Tertiary_operators

Operations Level 15

Operator Syntax Explanation
= a = b Assigns the value of "b" to "a"
+= a += b Assigns the value of "a + b" to "a"
-= a -= b Assigns the value of "a - b" to "a"
/= a /= b Assigns the value of "a / b" to "a"
*= a *= b Assigns the value of "a * b" to "a"
%= a %= b Assigns the value of "a % b" to "a"
<<= a <<= b Assigns the value of "a << b" to "a" ????????
>>= a >>= b Assigns the value of "a >> b" to "a" ????????
&= a &= b Assigns the value of "a & b" to "a" ?????????
^= a ^= b Assigns the value of "a ^ b" to "a" ?????????
|= a |= b Assigns the value of "a |= b" to "a" ??????????
