2. 获取 int32 范围的整数随机数,用 rand() 可能踩坑,建议获取浮点随机数后再转int 3. 获取 float 范围的浮点随机数,C++11 可以用 mt19937 + uniform_real_distribution 4. 获取 float 范围的浮点随机数,C/C++ 可以用 prng.h TAOCP 里公式的方式 0x5. 链接汇总...

@TD-er - Just to check the testing scripts, I confirm that using the proposed Sketch + Python, it always fails at some random time. After the FIX of the PR, it works always. Therefore, it shall be fixed for good. 👍 1 Contributor Author TD-er commented Mar 21, 2024 Thanks, ...

事实几乎如此——二进制文件包含了 CPU 执行的所有代码,但代码分散在多个文件中,方式非常复杂。链接是一个简化事物并使机器代码整洁、易于消费的过程。 快速查看命令列表会让你知道 CMake 并没有提供很多与链接相关的命令。承认,target_link_libraries()是唯一一个实际配置这一步骤的命令。那么为什么要用一整章来...
