C++异常处理基本句法测试

#include<iostream>
using namespace std;

int MyDivision(int a, int b)
{
    if (b == 0) {
        throw b;   //抛出异常
    }
    return a / b;
}
void test()
{
    int x, y;
    cin >> x >> y;
    try {   //试着捕获异常
        cout << "商为" << MyDivision(x, y) << " 。"<<endl;
    }
    catch (int e)   //捕获异常
    {
        cout << "除数为" << e << " !?" << endl;
    }

}
int main()
{
    test();
    return 0;
}
