Operators are symbols used to perform operations. There can be various types of operations, such as arithmetic, logical, bitwise, etc.
In C++, there are the following types of operators that perform different kinds of operations.
-
Arithmetic Operators
-
Relational Operators
-
Logical Operators
-
Bitwise Operators
-
Assignment Operators
-
Unary Operators
-
Conditional or Ternary Operators

Cpp Operators 1 – Operator Precedence in C++
The precedence of operators indicates which operator is executed first, followed by the next operator. Associativity specifies the direction of evaluation for operators, which can be left to right or right to left.
Let’s understand precedence through the following example:
int data=5+10*10;The “data” variable will contain 105 because the * (multiplication operator) is evaluated before the + (addition operator).
Here are the precedence and associativity of C++ operators:
| Category | Operator | Associativity |
|---|---|---|
| Postfix | () [] -> . ++ — | Left to Right |
| Unary | + – ! ~ ++ — (type)* & sizeof | Right to Left |
| Multiplicative | * / % | Left to Right |
| Additive | + – | Right to Left |
| Shift | << >> | Left to Right |
| Relational | < <= > >= | Left to Right |
| Equality | == != | Right to Left |
| Bitwise AND | & | Left to Right |
| Bitwise XOR | ^ | Left to Right |
| Bitwise OR | | | Right to Left |
| Logical AND | && | Left to Right |
| Logical OR | || | Left to Right |
| Conditional | ?: | Right to Left |
| Assignment | = += -= *= /= %= >>= <<= &= ^= |= | Right to Left |
| Comma | , | Left to Right |
