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
*/
