Withdraw numeral amount

hendrix33 (9)
Hey, everyone, I am trying to create a code that outputs a certain amount of money but can't be less than 1.00 or more than 300 dollars. For some reason, it's not stopping at those numbers during the test run it is still letting me input any amount.

A few small problems with this code and the text.

if (inputAmt==.99) cout << "please input a number greater than $1.00";
    if (inputAmt==301) cout << "Please input a number greater than or equal to $300.00";


Line 13 should be 
 
 
if (inputAmt < 1.00) cout << "please input a number greater than $1.00";

and line 14 should be..
 
 
if (inputAmt > 300.00) cout << "Please input a number less than or equal to $300.00";


You're also not reducing the variable 'remainderAmt' after finding the quantity of 20's, 10's etc.

EDIT..

Lastly, you should use a do/while around the input to be sure a valid amount was entered.

	do
	{
    cout << "Enter in the amount to be withdraw : " << endl;
    cin >> inputAmt;
    
    if (inputAmt < 1.00) cout << "please input a number greater than $1.00";
    if (inputAmt > 300.00) cout << "Please input a number less than or equal to $300.00";
	}while(inputAmt < 1 || inputAmt > 300);
