Re: argv[] comparison

* kaferro@hotmail.com:


Do the following:

   #include <iostream>

   #include <cstddef>
   #include <string>
   #include <vector>
   #include <stdexcept>

   typedef std::vector<std::string> StringVector;

   bool throwX( char const s[] ) { throw std::runtime_error( s ); }

   void cppMain( StringVector const& arguments )
   {
       arguments.size() > 1
           || throwX( "usage: myprog ARG1" );

       if( arguments.at(1) == "NKDT" )
       {
           // Do something.
       }
       else
       {
           // Do something else.
       }
   }

   int main( int n, char* a[] )
   {
       try
       {
           cppMain( StringVector( a, a+n ) );
           return EXIT_SUCCESS;
       }
       catch( std::exception const& x )
       {
           std::cerr << "!" << x.what() << std::endl;
           return EXIT_FAILURE;
       }
   }
