How many times can a file be compressed?

问题 I was thinking about compression, and it seems like there would have to be some sort of limit to the compression that could be applied to it, otherwise it\'d be a single byte. So my question is, how many times can I compress a file before: It does not get any smaller? The file becomes corrupt? Are these two points the same or different? Where does the point of diminishing returns appear? How can these points be found? I\'m not talking about any specific algorithm or particular file, just in

maximum value of int

Is there any code to find the maximum value of integer (accordingly to the compiler) in C/C++ like Integer.MaxValue function in java? Gregory Pakosz In C++: #include <limits> then use int imin = std::numeric_limits<int>::min(); // minimum value int imax = std::numeric_limits<int>::max(); std::numeric_limits is a template type which can be instantiated with other types: float fmin = std::numeric_limits<float>::min(); // minimum positive value float fmax = std::numeric_limits<float>::max(); In C: #include <limits.h> then use int imin = INT_MIN; // minimum value int imax = INT_MAX; or #include

Maximum size for a SQL Server Query? IN clause? Is there a Better Approach [duplicate]

问题 This question already has answers here : Closed 9 years ago . Possible Duplicate: T-SQL WHERE col IN (…) What is the maximum size for a SQL Server query? (# of characters) Max size for an IN clause? I think I saw something about Oracle having a 1000 item limit but you could get around this with ANDing 2 INs together. Similar issue in SQL Server? UPDATE So what would be the best approach if I need to take say 1000 GUIDs from another system (Non Relational Database) and do a \"JOIN in code\'

What is the maximum possible length of a .NET string?

问题 What is the longest string that can be created in .NET? The docs for the String class are silent on this question as far as I can see, so an authoritative answer might require some knowledge of internals. Would the maximum change on a 64-bit system? [This is asked more for curiosity than for practical use - I don\'t intend to create any code that uses gigantic strings!] 回答1: The theoretical limit may be 2,147,483,647, but the practical limit is nowhere near that. Since no single object in a
