13. A valid comment block in ASP.NET is (a)
Hi,
Following is the explanation for the answer (#50) of the question # 24.
There are common suffixes for each literal type. Suffixes ensure that the literal is the intended type. This is good for documentation. However, the primary benefit is ensuring that your expressions are evaluated correctly; that is, the compiler will interpret float and decimal literals without suffixes as a double when evaluating an expression. To avoid the associated errors, use an appropriate literal suffix.
