invalid_argument Class

The class serves as the base class for all exceptions thrown to report an invalid argument.

Syntax

class invalid_argument : public logic_error {  
public:  
    explicit invalid_argument(const string& message);

    explicit invalid_argument(const char *message);

};

Remarks

The value returned by what is a copy of message.data.

Example

// invalid_arg.cpp  
// compile with: /EHsc /GR  
#include <bitset>  
#include <iostream>  
  
using namespace std;  
  
int main( )  
{  
   try   
   {  
      bitset< 32 > bitset( string( "11001010101100001b100101010110000") );  
   }  
   catch ( exception &e )   
   {  
      cerr << "Caught " << e.what( ) << endl;  
      cerr << "Type " << typeid( e ).name( ) << endl;  
   };  
}  
\* Output:   
Caught invalid bitset<N> char  
Type class std::invalid_argument
