kandi X-RAY | array Summary

array is a C++ library. array has no bugs, it has no vulnerabilities and it has low support. However array has a Non-SPDX License. You can download it from GitHub.

Note: This project is currently WIP, no guarantees are made until an 0.1 release. This library is all about arrays — contiguous blocks of memory. It basically provides a customizable std::vector and containers built on top of it like flat sets and maps. The equivalent of std::vector — array — does not take an Allocator. Instead, it takes a BlockStorage. This policy is responsible for completely managing the underlying memory block: It stores the current address and size and has full control over reserve() and shrink_to_fit(). This makes it possible to have a fixed sized array, an array with small buffer optimization and much more just by swapping the policy.

            Return the range within an array Excel
            Asked 2021-Jun-16 at 02:47

            I need to retrieve a range delimited by indexes from a specific array

            I cannot use OFFSET because it doesnt use an array as a parameter. And the range will then be use for a secondary calculation

            The example:

            I want to calculate the SUM of the 4th to the 11th value in the column Numbers.

            So at the end the formula should look something like: =SUM(Numbers[4:10]) = 36 4 and 10 being the desired indexes.

            I tried with OFFSET and INDEX but cant figure out how to do it.

            Index(), INDIRECT() will work. Also OFFSET() will work but need to apply some trick. As @BigBen suggested you can use INDEX() like =SUM(INDEX(B:B,5):INDEX(B:B,11)) but I am sure you will not prefer to hard code index no. So, you can use below formula to dynamically input two index and get sum between those index. Try-

            You cannot compare two different objects using includes in javascript, because includes uses ===. Only references to the same object will return true using ===. You'll need to write a custom function that runs through all of the keys of your object and compares their values between your two arrays.

            Clang errors "expected register" with inline x86 assembly (works with GCC)
            Asked 2021-Jun-16 at 00:48

            I wrote a demo with some inline assembly (showing how to shift an array of memory right one bit) and it compiles and functions fine in GCC. However, the with Clang, I'm not sure if it's generating bad code or what but it's unhappy that I'm using memory despite the "rm" constraint.

            I've tried many compilers and versions via Godbolt and while it works on all x86/x86_64 versions of GCC, it fails with all versions of Clang. I'm unsure if the problem is my code or if I found a compiler bug.

            I'm unsure if the problem is my code or if I found a compiler bug.

            The problem is your code. In GNU assembler, parentheses are used to dereference like unary * is in C, and you can only dereference a register, not memory. As such, writing 12(%0) in the assembly when %0 might be memory is wrong. It only happens to work in GCC because GCC chooses to use a register for "rm" there, while Clang chooses to use memory. You should use "r" (bytes) instead.

            Also, you need to tell the compiler that your assembly is going to modify the array, either with a memory clobber or by adding *(unsigned char (*)[16])bytes as an output. Right now, it's allowed to optimize your printf to just hardcode what the values were at the beginning of the program.

            The issue you are having has nothing to do with templates. You cannot invoke std::async() on a member function without binding it to an instance. Wrapping the call in a lambda does the trick.

            I think the main misunderstanding is that my Int @a = 1,2,3 and [1,2,3] are somehow equivalent. They are not. The first case defines an array that will only take Int values. The second case defines an array that will take anything, and just happens to have Int values in it.

            I'll try to cover all versions you tried, why they didn't work, and possibly how it would work. I'll be using a bare dd as proof that the body of the function was reached.
