C/C+ 程序的最大堆栈大小?

Maximum Stack Size for C/C+ Program?(C/C+ 程序的最大堆栈大小?)

问题描述

我已经尝试了以下程序.创建此程序的目的是发现有关堆栈大小的更多信息.

I've tried the below program. The intent by which this program was created is to discover more about stack sizes.

int main()
{
    int nStack[100000000];
    return 0;
}

执行上述代码后，由于分配了巨大的堆栈大小，程序崩溃了.堆栈的最大可能大小是多少?它是否适用于每个程序/计算机?可以增加吗?

After executing the above code, the program crashes due to huge stack size allocation. What is the maximum possible size of the stack? Is it fixed for every program/computer? Can it be increased?

我想知道是为了知识.如果有人能提供 C/C++ 示例，那将非常有帮助.

I want to know for the sake of knowledge. If anyone can provide examples in C/C++, it would be very helpful.

推荐答案

我尝试了下面的程序.

int main()
{
    int nStack[519492];
    cout<<"Okay!";
    return 0;
}

输出:

Okay!

但是如果我将数组大小增加 1 个字节，程序就会崩溃.

But if I increase the array size by 1 byte, the program crashes.

int main()
{
    int nStack[519493];
    cout<<"Okay!";
    return 0;
}

输出:

No output. Program crashes.
