Literals and Constants in C#. Literal is a source code representation of a value, i.e. it is a value that has been hard-coded directly into your source. x is a variable, and 100 is a literal.
The literal value above is a floating point type. The value will be coerced by the compiler to fit into the int variable. For another example, in the first line of C++ code above the type of a string literal isn't actually the library type string at all.
