全局变量存放在程序的静态数据区，任何地方都能访问；static变量根据使用场景不同分为两种，static全局变量存在静态区，static局部变量虽然作用域受限，但也存在静态区。作用范围不同 全局变量默认具有外部链接属性，其他文件通过extern声明就能使用；static全局变量属于内部链接，只能在定义它的文件内部使用，其他文件无法访问...
Mixing inline and static will then have the consequences you described (even if the function is inlined, the static variable inside won't be, and you'll end with as much static variables as you have compilation units including the definition of your static functions). Answer to author's add...

Static variable declared once but its scope is life time of the program, that’s why on every call of the functionmyFunction()value ofvaris increasing. After removing the static from the declaration Let’s consider the program and output ...
