Suppose you need several possible values for a variable, then it can be defined as an enumeration type. The reason for enumeration is to enumerate the possible values of variables or objects.For example, to make everyone more clear, for example,

Using system. windows. forms; using system. runtime. interopservices; using system. io; [dllimport ("kernel32.dll", setlasterror = true)] Static extern int writeprofilestring (string lpszsection, string lpszkeyname, string lpszstring); [dllimport

When calling the join method of another thread in the first-line thread, the thread is blocked until the end of the other thread is executed, such as Java code.   Using system; Namespace testthreadjoin { Class Program { Static void main ()

Getopt (analyze command line parameters) Related Function header file# Include Define functionsInt getopt (INT argc, char * const argv [], const char * optstring ); Function DescriptionGetopt () is used to analyze command line parameters. The

Suggestions and rules Suggestion: Use inline or static functions to replace macros similar to Functions Add parentheses on both sides of macro parameter names Brackets should be added to the macro replacement list. Typedef should be used to

(1) Merge and sort Analysis: (1) division problem: divide the sequence into two halves with equal numbers of elements. (2) recursive solution: sort the two half elements separately. (3) Merge: merge two ordered tables into one. (You only need to

The problem is described as follows: Given a linked list, return the node where the cycle begins. If there is no cycle, return null.   Follow up: Can you solve it without using extra space?   From the perspective of the problem, it is not difficult

The question gives you a series, and each time the last number is raised to the beginning, until the original first number reaches the last one, each operation will generate a new series, this sequence has a value in the descending order and asks

Recently I was preparing to switch jobs. So I took a look at C ++ and made some exercises by the way, mainly in terms of data structure. I posted them here to make a series of exercises, so I can urge myself. On the first day, I wrote a stack,

1069-Always an integerGiven a polynomial, determine whether it is always an integer.Idea: the example in the LRJ White Paper shows that as long as the equation 1 to k + 1 (k is the maximum number of times) is an integer, then the entire equation is

The typical search problem is mainly time optimization. I used three secondary arrays to record information row [I] [k] = 1, indicating that row I number k has been used, col [j] [k] = 1 The number k in column j has been used, and blo [I] [k]

Int main () {Using namespace std;Int I = 20;Int m = (unsigned int) & I; // note the & SymbolCout } &: Indicates the meaning of the reference, indicating that m is an alias of I, which is equivalent to a small name of a person. Let's look at
