String.find (char *) to find if the string contains substringsFound: Returns the first indexNot found: Returns a large random number instead of returning negative numbers (this is a pit)So can't write if (String.find (str) > 0)This must be written if (String.find (str)! = NPOs)string S ("1a2b3c4d5e6f7g8h9i1a2b3c4d5e6f7g8ha9i");string Flag;string::size_type position;The //find function returns the subscript position of JK in Sposition = S.find ("JK");if (position! = S.npos)//If not found, return

the constant pool and return true.For System.out.println (E = = f); Their value is greater than 127, and returns false even if the values are the same but correspond to different memory addresses.For System.out.println (c = = (a+b)); They point to the same address in the constant pool and return true.For System.out.println (C.equals (a+b)); Their values are the same, and the same type, which returns TRUE.For System.out.println (g = = (a+b)); They point to the same address in the constant pool a

. Otherwise, c layer may get to be garbled.Question 4. Threading issues. Different threads use the Jnienv* object, which requires attachcurrentthread to hang the env to the current thread, or env cannot be used.Question 5. The JAVAP command is a class file operation on Java, and the Javah command needs to run in the package name to the previous path, otherwise the. h file cannot be generated.Question 6. Try to avoid frequent calls to JNI or to transfer large amounts of data using JNI.Question 7.

businesses in order to promote, before the event will quietly put the price of the original prices to increase, to the start of the activity discount price will be far lower than the original price of the same discount bid, And the average consumer is easily attracted by the low discount, so that they can sell a large number of products at a low price, thus obtaining high profits.2, the Ming Fall Dark RiseSome businesses are more thorough, not only no discount, but also the price is very high,

the IMyService lifetime scope, holds it come wrapped up together in a single object.The service implementation is available through the property Value :// Value is ImyserviceownedService.Value.DoSomething ();When the owned instance are no longer needed, it and all of their disposable dependencies can be released by disposing the object:Ownedservice.dispose ();Owner Instance is used in conjunction with fun:Components that is returned from Func delegates is associated with the same lifetime

are two kinds of integer arithmetic operations in C language, signed number and unsigned number operation.There is no overflow in the unsigned number operation, however the sign number operation may overflow when the result of an operation "overflows". It is unsafe to make whatever it is. The method that should be taken when encountering a possible overflow is to cast two operands A and B to an unsigned integer:if ((unsigned) A + (unsigned) b > Int_max)complain ();The Int_max here is a defined

| Xargs RMThis will execute the RM command for each file found, similar to the-exec function.However, the problem comes, when find found the path of the file has a space, xargs will divide the path into two segments, each paragraph as a parameter, the default xargs is the space to ask the segmentation basis.If you let the Xargs and find command take another special character as a delimiter, the problem is not solved, so that xargs will not misunderstand find.The find command can use the-PRINT0

1, compile stage, if not overloaded, then C-style function with the same name and C + + style of the same name, will be reported compilation error.Error c2084:function ' int Test (void) ' already has a body.2. During compilation, the compiler checks the functions in the namespace. such as Sg::test ();The compiler detects if there is a function test () in the SG namespace. If not, you will get an error.Error C2039: ' Test ': is not a member of ' SG '3, link stage, when the namespace is combined w

The 1004 question is actually very simple, is wants you to count the most balloons the number, but in the output time but needs to be careful carefully, conforms to the question request.In the output is the first note is the output order: If there are multiple numbers of the same color, first input first output, such as,RedGreenRedGreenThis situation requires an outputRedGreenPost the AC code:#include 　　Hangzhou Electric OJ 1004 realization and some traps
