statichas a very simple logic to it. If a variable isstatic, it means that it is a global variable, but it's scope is limited to where it is defined (i.e. only visible there). For example: Outside a function: g
char a = 'A'; // global variable void msg() { printf("Hello\n"); } 下面是main.c的内容 int main(void) { extern char a; // extern variable must be declared before use printf("%c ", a); (void)msg(); return 0; } 程序的运行结果是: A Hello 你可能会问:为什么在a.c中定义的...

to a static variable is changed by its storage mode, which 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. ...
