Here is an example of how you can use a static variable in C language −Open Compiler #include <stdio.h> int main(){ auto int a = -28; static int b = 8; printf("The value of auto variable: %d\n", a); printf("The value of static variable b: %d\n",b); if(a != 0)...

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,==...
within the function defining the variable. After exiting the function, you cannot use it even though it still exists.(2) allow the static class of a construction class to assign initial values, such as an array, if the initial value is not given, the system automatically assigns 0 values.
global variable could be calleda, while a static member of the class would be calledSomeClass::a. Besides scoped naming, there are no other differences. (I deliberately ignore other C++-specific features, like access control, since they don't exist in C and this question is really about C...

C/C++中static、const和inline三种关键字的介绍 一、关于static static 是C++中很常用的修饰符,它被用来控制变量的存储方式和可见性,下面我将从 static 修饰符的产生原因、作用谈起,全面分析static 修饰符的实质。 static 的两大作用: 一、控制存储方式
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中定义的全局变量a和函数msg能在main.c中使用?前面说过,所有未加static前缀的全局变量和函数都具有全局可见性,其它的源文件也能访问。
