What is the difference between Go's constant and literal values?

In Go, a constant value is a value that is assigned to a variable at compile time and cannot be changed during program execution. Constants are declared using the const keyword.

A literal value, on the other hand, is a value that appears directly in the code and is not assigned to a variable. For example, **"hello"** is a string literal, **42** is an integer literal, and **true** is a boolean literal.

Constants can also be created using literal values. For example, **const x = 42** declares a constant named **x** with a value of **42**. However, not all literal values can be used as constant values. Only certain types of literals can be used to define constants, such as boolean, numeric, and string literals.

One of the benefits of using constant values is that they provide compile-time checking and optimization, which can lead to more efficient code. Additionally, using constant values can help make code more readable and self-documenting, as it can make the meaning of values clearer.
