Web每个计算都是独立的,但我认为用 C++ x_i 重写这个循环可能会更快。 x_i 另一方面,如果我们在 C++ 中只有固定大小的数组,任务会变得更容易,这个循环也可以转移到 python。 这是我的问题的一些虚拟代码(I=5,J=3,K=2): // example.cpp #include #include #include #include … Webc++输入输出不用写类型,它自己知道类型. 5. 动态内存. 在 C++ 中申请内存使用的是 new. 销毁内存使用的是 delete. 我们用C和C++的方式分别申请和释放单个内存和整个数组. #include // printf () 用到. #include // malloc () free () 用到. #include // cout 用到.
