A string in the following format: ... ... ... (That is, strings can be viewed Start Substring at the end of the string ). Now I want: Input an index value (for example, I).

Ask everyone for a complicated PHP judgment question, thanks for the database's fields A, B, C, D, E, and F. assume that the F field content is 1, 2, 3, 4, 5, and 6 respectively. what we want to achieve now is when F when = 1, I output the content in F = 1 all A, B, C, D, and E. When F = 2, I output the content in F = 2 all A, B, C, and D. the content in E is as follows, thank you. The database has fields A, B, C, D, E, and F. Assume that the F fi

Here, I use reflection to provide a solution to give a key and call the function corresponding to the given key. In this way, the original problem is actually converted to the problem of using conditions to generate suit

))[10]; FP1 is near the right side, and * on the left side. Therefore, FP1 is a pointer. The parameter list (INT) on the right side of FP1 indicates that FP1 is a function pointer and the function parameter list is (INT ), therefore, the rest should be the return value of the function. If fp_ret is used to simplify the process, it can be expressed: Void* (* Fp_ret )[10]; Fp_ret is a pointer pointing to an array with a length of 10. The element type in the array is void *. Therefore, in combin

The first two of them are super complicated designs and completely do not comply with the open and closed principle. However, I think if I have never learned the so-called design patterns, I will never make the first two mistakes of "over-pattern. Therefore, the fans of design patterns should be careful to let youC

PHP's curl is not so complicated.

My younger brother just learned C/C ++ programming in Linux. My colleague told me to use makefile for compilation and asked me how to write makefile. A: makefile is very difficult, you can use a highly handwritten makefile from abroad for compilation. In doubt, open the so-called master makefile. It's really long and I don't understand it. If you are not convinced, go to the Internet to find some makefile tutorials, which are full of rankings that cannot be understood by file dependencies or tar

[Mac 10.7.1 lion intel-based x64 gcc4.2.1 xcode4.2] Q: What are the advantages and disadvantages of C ++'s default input and output and C? A: Any language has its own most recommended model, because the designer may have carefully considered it. There is no need to say which one is the best, which is the very bad, the best and the very bad have restrictions. Different users can always find the most suitable method. The input and output of C ++ is more object-oriented and modular. Its operations

Link: codeforces 467e Alex and complicated task Given a sequence of N lengths, select as many 4 tuples as possible (not overlapping ). Solution: The left end of every four tuples must be as small as possible. Therefore, a monotonous stack is used for maintenance. If the newly added number x appears in the stack, mark the number between two numbers as X. If the tag of a number is not empty, it means that the corresponding four tuples are found. Because

Benefits: 1. Make the process accessible faster. 2. Avoid the same last error. In projects, we sometimes encounter complicated logic (complicated process and logic ). This may cause the following problems. 1. It is difficult to enter some pictures. 2. Mistakes are easy to make. (We usually have evidence in the test. A. Have achievements in the process. B. There are also evidence of faults)

Regarding the use of the goto statement, it is difficult to use it technically. When I write this text about the use of the goto statement, I think it is difficult for beginners to grasp it if the goto is in another position from a complicated execution state. In a multi-nested loop judgment, the number of program execution paths is very large. After jumping out with the goto statement, it is difficult for beginners to find out if there are any proble
