上一周一直在dev、vc6.0、vs2010、vs2017之间挣扎，在我的win10虚拟机里无论哪个都有问题。

dev c++ debug彻底崩了，写c++的时候无法“下一步”；vc6.0 debug文件不存在；vs debug文件已过期。共同的问题是，多文件联编永远通不过编译?

终于趁着上机的时候问老师，解决了vc6.0的问题，但是无法单步调试。

vc 6.0的问题是，由于是虚拟机，所以一不留意就会存在着权限不够的问题。之前我使用默认存储路径，没有留意到路径是通到mac的文档里的。后来把路径调成win的C盘就好了。

说起来，我好像知道怎么调vs的问题了。之前照样调路径但是没用，现在想想可能跟安装文件在mac的文档里有关。

重点是，最后寄了点希望在code：：blocks上，结果非常好用。至少多文件联编没问题了，debug目前还没试，不过这个问题不大。

放一点纠结的时候码的东西吧：

明明觉得改了好久的error，但是回头写注释提醒的时候又觉得没什么。

这个程序觉得有点问题，感觉我是为了写题目而写，只能单人单次使用。想在学艺精湛之后结合文件，修改这个小项目。

求出现最频繁的数：

#include
     
      using namespace std;void fre(int *inte, int num);int main(){	int *num, count,i;	cout << "请问您要求多少个正整数的模？" << endl;	cin >> count;	cout << endl;	num = new int[count];	cout << "请输入一组正整数："<
      
       > num[i];		cout <
      
     

 这个很有问题，测试过程中有的正确，有的错误。错误主要集中在显示 没有最频繁的数（明明有！）可能是我逻辑和数学都不太好吧。先留个坑。
