Get acquainted with the C# language basics. Excerpt: C# supports both integral and floating-point numeric types, as well as a Boolean type, a Unicode character type, and a high-precision decimal type. These are referred to as the simple types. Associated with these types is a set of operators, including addition (+), subtraction (-), equality (==), and inequality (!=). C# provides a predefined set of statements as well, such as the conditional if and switch statements and the looping for, while, and foreach statements.
