问题 I'm working on a project that requires me to compile C++ code using MSVC, but I am working mostly with VSCode. As such, I was wondering if there is a way for me to add the Developer Powershell as an integrated terminal, so that I can compile without needing a secondary terminal open. I thought of just opening VSCode from the Developer PS itself, but since this is mostly a temporary project it seemed like a lot of repetitive work. I tried using the Shell launcher extension for VSCode but it

问题 I've looked at the other questions on this, all say install visual studio with c++, I have done this - 2017 version. I'm trying to build pypoisson in python3 which requires the c++ complier, I get this error: cl.exe /c /nologo /Ox /W3 /GL /DNDEBUG /MD -IC:\Users\garyn\PycharmProjects\pointcloudprocessor\venv\lib\site-packages\numpy\core\include -IC:\Users\garyn\PycharmProjects\pointcloudprocessor\venv\include "-IC:\Pr ogram Files\Python\Python37\include" "-IC:\Program Files\Python\Python37

问题 Consider this code: #include <stdio.h> int main(void) { /* TEST 1 */ double d = 128; char ch = (char)d; printf("%d\n", ch); /* TEST 2 */ printf("%d\n", (char)128.0); /* TEST 3 */ char ch1 = (char)128.0; printf("%d\n", ch1); return 0; } Results: gcc* clang* cl* TEST 1 -128 -128 -128 TEST 2 127 0 -128 TEST 3 127 -2 -128 * latest version Questions: Why the results differ between tests (excluding cl )? Why the results differ between compilers (excluding TEST 1 )? In case of UB/IB, where is the UB

问题 When I compile a simple program: #include <iostream> using namespace std; void main() { cout << "Hello world!"; } And tun the compiled .exe on another system without visual studio installed I receive the following error: The Code execution cannot proceed because VCRUNTIME140.dll was not found. Reinstalling the program may fix the problem. When I compile with cl.exe I receive no errors, does anyone know a workaround to this without installing VCRUNTIME140.dll on the systems. (I've tested on
