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(). For more information, see what and data.

Example

// invalid_argument.cpp
// compile with: /EHsc
#include <bitset>
#include <exception>
#include <iostream>
#include <typeinfo>
using namespace std;

int main()
{
   try
   {
      bitset<32> b("11001010101100001b100101010110000");
   }
   catch (const exception& e)
   {
      cerr << "Caught: " << e.what() << endl;
      cerr << "Type: " << typeid(e).name() << endl;
   }
}
/* Output:
Caught: invalid bitset char
Type: class std::invalid_argument
*/
