Logical and Assignment Operators

In this lesson, we’ll explore logical and assignment operators. By understanding logical operators, we’ll learn how to create complex conditions by combining boolean values. Simultaneously, we’ll learn assignment operators, simplifying the process of modifying variables.

Logical operators

These operators are used to pair two or more conditions together. The following logical operators are supported by Solidity:

• AND (&&): This returns true if both criteria are true and false if just one of them is true.

• OR (||): This returns true when one or both criteria are met and false when both are not.

• NOT (!): This returns true if the condition is not met. Otherwise, false.

The following code example demonstrates the use of logical operators in Solidity:
