Storage location of C++ array in memory

This question already has an answer here:

Where are static variables stored (in C/C++)? 16 answers

---

a static array (declared at a global scope or in a namespace) will be placed in the data segment. A local array declared inside a function scope will be placed on the stack.

int g_global_array[2] = {4,5,6};  //Data Segment
int main() {
     int local_array[3] = {1,2,3};  //Stack
     static int s_static = 10; //Also in the Data Segment (static)
     return 0;
}

(Same as in plain old C)

是的，以这种方式声明的本地数组将被存储在堆栈中并具有固定长度。

A local array is addressed in the stack. There is a constant size which can't be increased. If you write more values in the array than it can contain, there will be a so called stack overflow. Behind them fields, there is the memory of other values which would be overwritten then. Visual Studio creates some protection bytes to avoid this.
