C Language provides a rich collection of operators. Here in this post we will see the operators supported in C-language, type of operators and precedence of operators
Operators in C
Operators use one or more operands to perform an action. Operators are symbols that inform to the computer to carry out operations with operands. The operations could be mathematical, logical or relational. C Language provides a rich set of operators.
Types of Operators in C
The Operators are categorized in the following on the basis of use.
- Arithmetic operators
- Relational operators
- Logical operators
- Unary operators
- Conditional operator
- Assignment operators
- Bitwise operators
- Other operators
Precedence of Operators in C
The Precedence of Operator determines order of the operators to be evaluated in an expression. Operations may be evaluated in two directions, left to right and right to left.
The table below illustrates the precedence of the operators and it’s direction of evaluation.
| Category | Operators | Directions |
| Group | ( ) [ ] | Left to right |
| Postfix | -> . | Left to right |
| Postfix | ++ — | Left to right |
| Unary | + – ! ~ | Right to Left |
| Prefix | ++ — | Right to Left |
| Unary | (type)* sizeof | Right to Left |
| Multiplicative | * / % | Left to right |
| Additive | + – | Left to right |
| Shift | << >> | Left to right |
| Relational | < <= > >= | Left to right |
| Equality | == != | Left to right |
| Bitwise AND | & | Left to right |
| Bitwise XOR | ^ | Left to right |
| Bitwise OR | | | Left to right |
| Logical AND | && | Left to right |
| Logical OR | || | Left to right |
| Conditional | ?: | Right to Left |
| Assignment | = += -= *= /= %=>>= <<= &= ^= |= | Right to Left |
| Comma | , | Left to right |
