C++ catch 块没有捕获异常

Question

下面的代码仍然崩溃，而不是有 try-catch 块。我在 Window 10 上使用 g++ 编译器。

#include <iostream>
using namespace std;


int main() {
    int top = 90;
    int bottom = 0;

    try
    {
        cout << "top / 2 = " << (top / 2) << endl;

        cout << "top divided by bottom = ";
        cout << (top / bottom) << endl;

        cout << "top / 3 = " << (top / 3) << endl;
    }
    catch(...)
    {
        cout << "something has gone wrong!" << endl;
    }
    cout << "Done." << endl;
    return 0;
}

然后我尝试了以下操作：

#include <iostream>

int main() {
    try {
        throw 0;
    }
    catch(...) {
        std::cout << "Exception occured"! << endl;
    }
    return 0;
}

这个很好用。我的意思是这里的 catch 块捕获抛出的异常。
