Question 6

Which of the following statements is false

Accepted Answer

A)  C# does not include an exponentiation operator. 
B)  The expression
Math.Pow(x, y)

C)  C# will implicitly convert a double to a decimal, or vice versa. 
D)  In loops, avoid calculations for which the result never changes-such calculations should typically be placed before the loop. Optimizing compilers will typically do this for you.
