从stack / bss分配的变量?? [英] variable allocated from stack/bss ??
问题描述
鉴于以下代码&变量i。
int main（int argc，char ** argv）{
int i;
printf（" ％d \ n"，i）;
返回0;
}
这里我从bss或堆栈分配？
我认为它是堆栈，因为它打印垃圾值;如果从bss分配
，默认值为0
请告诉我，如果我是对还是错？
Given the following code & variable i .
int main(int argc,char **argv){
int i;
printf("%d\n",i);
return 0;
}
here i is allocated from bss or stack ?
I think it is stack,because it prints garbage value; If it were
allocated from bss the default value would be 0
please tell me if I am right or wrong ??

局部变量存储在堆栈中。 BSS用于未初始化的全局或静态变量。
Local variables are stored on the stack. BSS is used for uninitialized
global or static variables.

本地变量存储在堆栈中。

C标准并不要求你的实现有bss或堆栈。
然而，它确实要求你为printf提供一个合适的原型，
它还要求你不要评估不确定价值的

The C Standard doesn''t require your implementation to have a bss or a stack.
It does require, however, that you provide a proper prototype for printf,
and it also requires that you don''t evaluate indeterminately-valued
objects.
