(1) a static local variable defines its lifetime in the function as the entire source, but its scope remains the same as that of the automatic variable, and can only be used within the function defining the variable. After exiting the function, you cannot use it even though it still ...

changes its lifetime. Changing a global variable to a static variable changes its scope and limits its use. So the role of static this descriptor is different in different places. 4. Static function ... internal and external functions

静态变量static variable指的是该变量在内存中原地不动,而非说它的值不变。 块作用域的静态变量在程序离开他们所在的函数后,这些变量并不会消失,计算机在多次调用之间也会记录它们的值。 另外,对于块作用域的变量而言,非静态变量每次它的函数被调用时都会初始化该变量,但是静态变量在编译它的函数时只初始化一次,=...
关于静态变量(static) 总结: 1、静态局部变量和普通局部变量不同。静态局部变量也是定义在函数内部的,静态局部变量定义时前面要加static关键字来标识,静态局部变量所在的函数在多调用多次时,只有第一次才经历变量定义和初始化,以后多次在调用时不再定义和初始化,而是维持之前上一次调用时执行后这个变量的值。本次接着...
