A value that’s initialized once and cannot change, indicated in Swift by the let keyword.

A constant is a value that the programmer cannot change, for example numbers (1, 2, 42). With variables, on the other hand, the programmer can assign a new value to a variable name already in use. Lik [..]

In programming, a constant is a value that never changes. The other type of values that programs use is variables, symbols that can represent different values throughout the course of a program. A con [..]

A letter or symbol whose value always stays the same. The constant Π is a common example.

In math, things that do not change: for example distance, volume, mass, are called constants. The things that do change are called variable. constant functions:

In the context of C#, a constant is a type of field or local variable whose value is set at compile time and can never be changed at run time. It is similar to a variable by having a name, a value, an [..]
