[ad_1] First of all not all variables can be made constexpr. For example int x; std::cin >> x; Obviously x cannot be constexpr. The value it will have after it has been read from input is not a compile-time constant. Second, constexpr is part of the contract of a variable or function. By marking it … Read more
[ad_1] The correct (standard) way to do this on C and Windows is with __beginthreadex. This is usually preferred to calling CreateThread directly as CreateThread doesn’t init C runtime support for the thread. So if you create a thread using CreateThread, and call a CRT function, bad stuff can/will happen. Note that __beginthreadex calls CreateThread … Read more
[ad_1] There’s no such thing as a member function of a raw array. The sub-expression detectionMethods refers to the raw array and decays to a pointer to the first item. The rest, ->length(), calls a member function of the first item. One easy way to avoid these problems is to use std::vector instead of a … Read more
[ad_1] As the man page for free will tell you, any argument except a pointer returned from malloc has undefined behaviour: The free() function frees the memory space pointed to by ptr, which must have been returned by a previous call to malloc(), calloc() or realloc(). Otherwise, or if free(ptr) has already been called before, undefined behavior occurs. If ptr is NULL, no operation … Read more
[ad_1] As others have pointed out sorting and removing duplicates is possible. But how about this algorithm (in pseudocode, implementation is left to the reader)? bool contains(int x, int digit); // returns true if x contains digit in base 10 notation int res = 0; for (int digit = 0; digit <= 9; ++i) { … Read more
[ad_1] Use BigInteger.Parse with a style of NumberStyles.HexNumber: using System; using System.Globalization; using System.Numerics; class Program { static void Main() { var number = BigInteger.Parse(“728faf34b64cd55c8d1d500268026ffb”, NumberStyles.HexNumber); Console.WriteLine(number); } } Output: 152278043568215137367088803326132908027 [ad_2] solved Convert string BigInteger with base 16 in c#
[ad_1] The return type of std::queue::pop() is void. Hence, you may not use: reverse.push(Q.pop()); You can use: reverse.push(Q.front()); Q.pop(); 0 [ad_2] solved Invalid use of void expression with a Queue and .pop()
[ad_1] Yes you can, and it’s actually enforced really well (unlike gcc/clang etc, where __attribute__((always_inline)) is unfortunatly still optional for the compiler, depending on multiple other compiler flag settings). The keyword works in all versions of Visual Studio. [ad_2] solved VS __forceinline in cpp [closed]
[ad_1] You are running the gcc command from the home directory (~) when the hello.c file is in ~/Documents. Either navigate to Documents using cd before running gcc or place hello.c in the home directory. 7 [ad_2] solved Getting two errors while compiling C code on a Linux virtual Machine
[ad_1] Assuming your pool of characters is sorted and without repetitions (may need some preprocessing), generating the desired strings in lexicographic order is automatic (in the approach I have in mind). Look at the short example of all nonempty strings that can be generated from “ABC” with the restrictions: A AB ABC AC ACB B … Read more

[ad_1] Well I just had a quick look at that monstrosity, and I’m not going to look too far into it but right off the bat I see a problem. I don’t know if this is related to this particular problem you are asking about, but this type of thing isn’t going to work the … Read more
[ad_1] it was a problem with my Include directories in VisualGDB Properties–>Makefile settings. I was adding a new directory for each library I got. I reinstalled VS2015, but that did nothing because the culprit was a project option. I copied the default* include directories and that was it. *someone on my team provided me with … Read more
[ad_1] It’s public: and not Public:. Because dd is part of A, you need an instance of A to access dd. 1 [ad_2] solved c++ access stuff out side the class [closed]
