Logical Operators
The following table shows all the logical operators supported by C language.
Logical Operator And (&&)
| Operator | Description |
| && | Called Logical AND operator. If both the operands are non-zero, then the condition becomes true. |
Truth Table
| condition 1 | condition 2 | result(condition1 && condition 2) |
| True (1) | True(1) | True (1) |
| True(1) | False(0) | False(0) |
| False(0) | True(1) | False(0) |
| False(0) | False(0) | False(0) |
Logical Operator Or (||)
| Operator | Description |
| || | Called Logical OR Operator. If any of the two operands is non-zero, then the condition becomes true. |
Truth Table
| condition 1 | condition 2 | result (condition 1 || condition 2) |
| True (1) | True(1) | True (1) |
| True(1) | False(0) | True(1) |
| False(0) | True(1) | True(1) |
| False(0) | False(0) | False(0) |
Logical Operator Not (!)
| Operator | Description |
| ! | Called Logical NOT Operator. It is used to reverse the logical state of its operand. If a condition is true, then Logical NOT operator will make it false. |
Truth Table
| Condition | result (! condition) |
| True (1) | False (0) |
| False (0) | True (1) |
Note:
If the value is Non zero it means True (1)
if the value is Zero it means False (0)
