Using literals

Solidity provides the use of literals for assignments to variables. Literals do not have names; they are the values themselves. Variables can change their values during program execution, but a literal retains the same value throughout. Take a look at the following examples of various literals:

• Examples of integer literals are 1, 10, 1,000, -1, and -100.
• Examples of string literals are "Ritesh" and 'Modi'. String literals can be in single or double quotation marks.
• Examples of address literals are 0xca35b7d915458ef540ade6068dfe2f44e8fa733c and 0x1111111111111111111111111111111111111111.
• Hexadecimal literals are prefixed with the hex keyword. An example of a hexadecimal literal is hex"1A2B3F".

Solidity supports decimal literals with the use of the aa dot – examples include 4.5 and 0.2.

This concludes the details about declaring and using literal values within smart contracts. Now, it's time to move...
