在抛出std :: exception的实例后终止调用

Question

我是异常的新手，我试图改进我的一位朋友在求职面试中提出的问题解决方案。

我的朋友被要求构建一个程序，它将获得2个数组并找到一个数字，如果我们将它除以第一个数组的成员，我们将获得第二个数组的匹配剩余部分。

在这种情况下，我可以使用std :: exception而不使用任何继承类吗？

CPP文件

#include <iostream>
#include <exception>
#include "FindNumber.h" 


Finder::Finder() : m_num(0)
{}


int Finder::FindFirst(int* _divided, int* _leftOver, int _size)
{
    int indx = 0;

    while(indx < _size)
    {

        if (!_divided[indx])
        {
            throw("Can not divide by zero!!");
        }

        if (m_num % _divided[indx] != _leftOver[indx])
        {
            ++m_num;
            FindRest(_divided, _leftOver, _size);
            indx = 0;
        }

        ++indx;
    }

    return m_num;
}


int Finder::FindRest(int* _divided, int* _leftOver, int _size)
{
    int indx = 0;

    for(;;)
    {
        if (!_divided[indx])
        {
            throw("Can not divide by zero!!");
        }

        if (m_num % _divided[indx] != _leftOver[indx])  
        {
            ++m_num;
        }
        else
        {
            break;
        }
    }

    return m_num;
}
