The 1.static global variable is only initialized once, preventing it from being referenced in other file units;2.static Local variables are initialized only once, the next time based on the last result value;The 3.static function has only one copy

For a complete program, the distribution in memory is as follows:The dynamic data generated by new in the general program is stored in the heap area, and the automatic variables inside the function are stored in the stack area. Automatic variables

The initialization of a static local variable inside a function is performed when the function is first called; It is not initialized in subsequent calls. In a multithreaded environment, it is still possible to ensure that static local variables are

Static variables are scoped to a file, space is allocated at the beginning of the program, Space is freed at the end, default is initialized to 0, and its value can be changed when used.static variables or static functions only the code in this file

1, can local variables and global variable duplicate? A: Yes, the local will screen the overall situation. To use a global variable, you need to use the "::" Local variables can have the same name as global variables, and when referenced within a
