Today, in C #, you encounter a problem that requires you to convert a double to a string display, requiring you to keep the decimal digits.Check out the relevant articles on the InternetSpecific as follows:Double temp=3.1415926;F Fixed point:string str1=temp.tostring ("F1");//Keep one decimal rounding Result: 3.1F Fixed point:string str2=temp.tostring ("F2");//reserved Two decimal places, rounding the following analogy results: 3.14N Number:string str2=temp.tostring ("N");//retention Result: 3.1

++, finally a=3;S[0]=0S[1]=0S[2]=0S[3]=3A = 3Note: The first two times ++a, A=3; Then carry on the s[3]=3;Summary: In the above-mentioned formula with increment operation, before the assignment operation, all the ++x is done, and the value of the variable is saved. The assignment operation is in progress.After the assignment operation is done, the increment operation of x + + is performed. This will explain all the running results above.(PS: You can use the above code to run the results to exami

So this involves a recursive invocation of something.Here is a deep copy function I implemented, you can write your own and then add to your own node.
