1. Introduction Example
We know that if you have a thin sheet with mass density on the surface, the mass of the plane slice can be represented by the following double integral
When it is a space surface with mass density, it also has mass, so how does it define and calculate its mass? Obviously, the solution to this problem is still available in the element method we have used repeatedly.

In C ++, memory is divided into five areas: heap, stack, free storage, global/static storage, and constant storage.Stack is the storage area for variables that are automatically allocated by the compiler when necessary and clear when not needed. The variables are usually local variables and function parameters.Heap is the memory blocks allocated by new. Their release compilers are not controlled and controlled by our applications. Generally, a new com

The memory occupied by a C/C ++ compiled program is divided into the following parts:1. STACK: the stack zone is automatically allocated and released by the compiler, and stores function parameter values and local variable values. The operation method is similar to the stack in the data structure.2. Heap-generally assigned and released by the programmer. If the programmer does not release the heap, it may be recycled by the OS at the end of the program. Note that it is different from the heap in

Once the memory area is mapped to the address space of the process that shares it, the transfer of inter-process data no longer involves the kernel . However, there is usually some form of synchronization between the processes that store or take information from the shared memory
