Operators in Go
Operators are symbols that perform operations on variables and values. Go supports various types of operators used in expressions.
1. Arithmetic Operators
| Operator |
Description |
Example |
| + | Addition | a + b |
| - | Subtraction | a - b |
| * | Multiplication | a * b |
| / | Division | a / b |
| % | Modulus (remainder) | a % b |
2. Relational (Comparison) Operators
| Operator |
Description |
Example |
| == | Equal to | a == b |
| != | Not equal to | a != b |
| < | Less than | a < b |
| <= | Less than or equal to | a <= b |
| > | Greater than | a > b |
| >= | Greater than or equal to | a >= b |
3. Logical Operators
| Operator |
Description |
Example |
| && | Logical AND | a && b |
| || | Logical OR | a || b |
| ! | Logical NOT | !a |
4. Assignment Operators
| Operator |
Description |
Example |
| = | Assign | a = b |
| += | Add and assign | a += b |
| -= | Subtract and assign | a -= b |
| *= | Multiply and assign | a *= b |
| /= | Divide and assign | a /= b |
| %= | Modulus and assign | a %= b |
5. Other Operators
& : Address of a variable (pointer).* : Dereference pointer to get value.<< : Left shift.>> : Right shift.^ : Bitwise XOR (exclusive OR).^= : Bitwise XOR and assign.
Note: Go does not support the increment (++) or decrement (--) operators as expressions; they can only be used as standalone statements.
