@文心快码iso c++ forbids variable length array 文心快码 在C++编程中,了解变长数组(Variable Length Arrays, VLA)及其限制是非常重要的。以下是针对你问题的详细解答: 1. 什么是变长数组 变长数组是指在声明时,其大小不是固定的,而是由一个变量决定的数组。例如,在C语言中,你可以这样声明一个变长数组: c ...
It seems that I can use OpenMP together with CilkPlus array notation on variable length arrays, but not _Cilk_for. This is under the Intel compiler with build 13.1.2.183. I get messages like: junk.cpp(10): error: a variable captured by a lambda cannot have a type involving a variable...
Variable-length arrays (VLAs) are neither part of Cilk Plus nor part of standard C++. The Intel compiler supports a subset of VLAs in C++ mode and g++ supports a smaller subset, but this support is not considered part of Cilk Plus, though I agree that it does make a nice combination...
How do I allow the user to pass input to an array of characters where the length of that input can vary? I have something like this. 1 2 3 4 5 6 7 8 9 10 11 12 #include <iostream>usingnamespacestd;intmain(intargc,char* argv[]) {chara[12];for(inti = 0; i < 12; i++)...
In linux gcc, you can create an array and use a variable as size. When you try to do the same in Visual Studio, IntelliSense says that expression must have a constant value. I've researched about it, but it's still not clear to me why this happens in Visual Studio. Is there...
As far as I know, variable length array is not a part of C++ standard, it is a GCC extension. To an extent, clang supports VLA too, but it does not support initialization of such arrays.Author jetcoder commented Apr 3, 2021 • edited There is an example in C++14 standard (N3690...
Have look athttps://code.sololearn.com/cph9OWr5ZD0Y/?ref=app#cppYour code has several problems. I tryed to fix them. Your initial problem was to detect the length of the array. In C and C++ this is not so easy. Normally you could put a sentinal value as last entry in the array...
