data storage programs

programmer applies for allocation and release. The heap is growing from a low address bit to a high address bit, using a chained storage structure. Frequent malloc/free cause a discontinuity in memory space, resulting in fragmentation. When applying for heap space, the library function searches for a sufficient amount of space available in accordance with a certain algorithm. So the heap is much less efficient than the stack.The source file that will

amount of space available in accordance with a certain algorithm. So the heap is much less efficient than the stack. The source file that will reflect C corresponds to the storage space:At this point the program has not been put into memory, but in the case of hard disk storage, BSS does not occupy space at this time. BSS gets a memory space when it is linked.Indicates that the program is running, that is,

From low address to high address:1. Code area "contains constant": binary code that holds the body of the function2. Global variable Area "initialized + uninitialized":The storage of global variables and static variables is put together, initialized global variables and static variables in an area, uninitialized (global variables and static variables) in another adjacent area. System released after the program is finished3, Heap: by the programmer ass

You may often encounter the need to access program configuration files in Java programs, for example, in order to be able to connect with different databases, we often deposit the information of the database connection into the property file, which generally includes the database driver class name, the database connection URL, the database username and password, and so on. In order to facilitate the installation or deployment of
