solidity memory vs storage

The memory manager of PHP is hierarchical. This manager has three layers: storage, heap, and emalloc/efree. The storage layer uses functions such as malloc () and mmap () to apply for memory from the system, and releases the applied memory through the free () function. The

string constant store, and the compiler may optimize it with the "123456" that P3 points to as a blockreturn 0;}In the C + + language, similar to C, but also different, memory is mainly divided into the following 5 storage areas:(1) Stack: a local variable within a function (including a function argument), the compiler is responsible for allocating the release, the function ends, and the stack variable is

This article from http://soft.chinabyte.com/database/176/11595176.shtml 1. In C, these storage areas are divided 1. Stack-automatically allocated and released by the compiler 2. Heap-generally 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. 3. in the global zone (static zone), global variables and static variables are stored in one partition, and initialized global variab

memory-intensive process, you need to make large-scale memory release so that the process can run, and secondly, in physical memory, the different processes are "visible", that a process can be "access" in some way Other processes, which creates a great deal of insecurity. Virtual memory/Virtual

INNODB storage EngineInnoDB to MySQL provides transactional, rollback , crash- repair , and Multi-version concurrency control transaction security. In MySQL starting from 3.23.34a contains Innnodb. It is the first table engine on MySQL to provide a foreign key constraint. and InnoDB's ability to handle transactions is unmatched by other

I. Basic Memory StructureThe programmable memory can basically be divided into the static storage area, heap area, and stack area. Their functions are different, so they are used differently.Static storage zone: it is allocated when the program is compiled, and the existing program exists throughout the runtime. It sto
