Error output

[CombatJ]

I would like to ask how I could make this condition

int input;

cin >> input;

If (input is not an int type )
{cout << "error" << }

else { cout << "your input is an int type" << endl;}

This is supposed to be a part of a code I'm making that when the user types in an invalid input, there will be an error message then the computer will redo the loop statement.

Thanks for reading!
