logic_error Class
The latest version of this topic can be found at logic_error Class.
The class serves as the base class for all exceptions thrown to report errors presumably detectable before the program executes, such as violations of logical preconditions.
Syntax
class logic_error : public exception {
public:
explicit logic_error(const string& message);
explicit logic_error(const char *message);
};
Remarks
The value returned by what is a copy of message.data.
Example
// logic_error.cpp
// compile with: /EHsc /GR
#include <iostream>
using namespace std;
int main( )
{
try
{
throw logic_error( "logic error" );
}
catch ( exception &e )
{
cerr << "Caught: " << e.what( ) << endl;
cerr << "Type: " << typeid( e ).name( ) << endl;
};
}
Output
Caught: logic error
Type: class std::logic_error
