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(). For more information, see what and data.
Example
// logic_error.cpp
// compile with: /EHsc
#include <exception>
#include <iostream>
#include <stdexcept>
#include <typeinfo>
using namespace std;
int main()
{
try
{
throw logic_error("Does not compute!");
}
catch (const exception& e)
{
cerr << "Caught: " << e.what() << endl;
cerr << "Type: " << typeid(e).name() << endl;
}
}
/* Output:
Caught: Does not compute!
Type: class std::logic_error
*/
