1.默认初始化为0: 如果不显式地对静态变量进行初始化,它们将被初始化为0。 static变量存放在Global/Static(全局区/静态区)。在静态数据区,内存中所有的字节默认值都是0x00,所以在程序一开始时static声明的变量会被默认初始化为0。 2.static声明的变量会一直保持其值(局部静态对象) static变量存放在Global/Static...
return&Data;//Address of local variable } intmain() { //Returning address of the local variable int*piData =Fun(); printf("%d", *piData); return0; } Answer: ? Q15: Can we access a global variable if there is a local variable with the same name in C?

Here is the output of the global variable illustration. First, the compiler will execute the global variable “y” because it was declared first in the program; after the implementation of the increment operation, variable “y” will become “11,” and then the function is called, which is ...
Global variable:文件作用域:可以加上extern声明为外部变量,跨文件作用域(这里指的是把这些变量定义在.cpp文件中) static (Global) Function:有文件作用域,只在本文件中使用 Global Function:无文件作用域 static Member (in Function) variable:函数调用完成后,变量保存状态,再次调用函数,不会重新分配空间 ...
(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 ...

C Learner November 21, 2024 10:47 am imagine static global variables that declared and defined in header. In this case it's completely pointless that this global variable became internal linkage because wherever I include this header, I will always be able to access this static global variab...
