Can you help me to solve this?

"Create a program that allows to type a old password then it should creates a new password. All vowel letter should Replace with letter X and all numbers should replace with letter Z. New password must be done in reversed".

I have a code of this but I dont know how to reverse.

#include<iostream>
#include<string>
using namespace std;


int main()

{
long loop = 0;
int k = 0;
int count = 0;

while (loop>-1)

{
string input;
cout << "Enter Original Password (Enter -1 to end): ";
getline(cin, input);


if (input == "-1")
{
break;
}
count = input.length();


for (k = 0; k < count; k++)
{
if (input[k] == 'a' || input[k] == 'A' || input[k] == 'e' || input[k] == 'E' || input[k] == 'i' || input[k] == 'I' || input[k] == 'o' || input[k] == 'O' || input[k] == 'u' || input[k] == 'U')
{
input.replace(k, 1, "X");
}
if (input[k] == '1' || input[k] == '2' || input[k] == '3' || input[k] == '4' || input[k] == '5' || input[k] == '6' || input[k] == '7' || input[k] == '8' || input[k] == '9' || input[k] == '0')
{
input.replace(k, 1, "Z");
}



}
cout << "Your New Password:" << input << endl;


}
system("pause");

}



The output should be this:

Enter Original Password (Enter -1 to end): A1 qw2
Your New Password: Zwq ZX
Enter Original Password (Enter -1 to end): aap2
Your New Password: ZpXX
Enter Original Password (Enter -1 to end): -1
