是否在存储在堆栈上的函数中声明了 const 数组? [英] Are const arrays declared within a function stored on the stack?

问题描述

如果这是在函数中声明的，它会在堆栈上声明吗?(它是 const 是什么让我想知道)

if this was declared within a function, would it be declared on the stack? (it being const is what makes me wonder)

void someFunction()
{

     const unsigned int actions[8] = 
     {       e1,
             e2,
             etc...
     };
 }

推荐答案

是的，它们在堆栈中.您可以通过查看此代码片段来了解这一点:它必须打印 5 次销毁消息.

Yes, they're on the stack. You can see this by looking at this code snippet: it will have to print the destruction message 5 times.

struct A { ~A(){ printf( "A destructed\n" ); } };

int main() {
    {
      const A anarray  [5] = {A()} ;
    }
    printf( "inner scope closed\n");
}
