我的代码中有什么错误会导致异常被忽略？

Question

我正在实施一些程序错误异常捕获，但它无法正常工作，因此我发现我的代码中有任何错误，编译器也没有显示任何警告和错误。程序构建成功，但忽略异常。

#include <iostream>
#include <string>
using namespace std;

void wrongUsage()
{
   bool erroCode = true;
   bool errorMessge = true;
   bool stringError = true;

   if(erroCode)
   {
      throw 7;
   }else if (errorMessge)
   {
      throw "Something went wrong in Character message";
   }else if(stringError)
   {
      throw string ("Something else wrong happened in the string area");
   }
}

void programErrorExceptions()
{
   void wrongUsage();
}

int main()
{
   try {
      programErrorExceptions();
   }
   catch (int err)
   {
      cout << "Code Exception occurred: " << err << '\n';
   }
   catch (char const *err)
   {
      cout << "Msg Exception occurred: " << err << '\n';
   }
   catch (string &err)
   {
      cout << "Strmsg Exception occurred: " << err << '\n';
   }

   return 0;
}

更正以下内容

void programErrorExceptions()
{
   void wrongUsage();
}

至

void programErrorExceptions()
{
   wrongUsage();
}

我的代码中有什么错误会导致异常被忽略？

What error in my code I have which cause exceptions ignored?
