Recommendation 7: Use the 0 value as the default value for the enumerationThe enumeration types allowed are byte, sbyte, short, ushort, int, uint, long, and ulong. You should always use a value of 0 as the default value for the enumeration type. However, this is not done because the default value for the enumeration type that is allowed at the time of declaration is 0

Idea: Preliminary view it is difficult to analyze the meaning of the expression at a glance, we might like to analyze the example, assuming that n = 5, the binary is represented as 101, then n-1 = 4, the binary is expressed as, 5 4 = 101 100 = 100 = 4! = 0, let's look at more examples below5 4 101 - 4 6 5 the 101 4 7 6 111 the 6 8 7 + 0111 0We will find that to make the expression equal to 0,n-1, we m

If a new HANDLE is introduced in each step, subsequent cleanup will become very heavy. Someone recommends do... The while (0) structure. Someone recommends goto. The two forms are -

After seeing the topic, analysis, the factorial of 10 is already very big. The calculation of the end of the number of 0, completely unrealistic, even if the implementation is also very troublesome.
Later, when you think of a number in the factorial of the product has 5 end of the number should be at the end of the result of a 0.
Put it into practice, test a few, no mistakes.
