It's not working, god I suck. I should reread the entire book.

Code:
int main()
{
 ofstream outfile ("IntegerProgram.txt"); //Creates textfile
 cout << "This is the semi-godlike Integer Detection Program. It will allow you to enter a number, then determine if  the entered number is an intege.\n";


float integer;
int remainder = (int)integer;

cout << "Please enter your number: ";
 cin >> integer;

 remainder = integer%1;

 if(remainder == 0)
 {
  cout << "Yes, " << integer << "is an integer.";
 }
 else
 {
  cout << "I'm sorry, " << integer << "is not an integer.";
 }


 getch();
 return 0;
 }
