Prompt User to Loop - c++

Question

I have created a Prompt User to Loop to restart the program however when I type anything including "y" it just goes prompts me with "Press any key to continue . . . " and then closes. Here's my code:
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main()
{
int Multiple1 = 0;
int Multiple2 = 0;
char again = 'Y';
while (again == 'y' || again == 'Y')
{
int Multiple1 = 0;
int Multiple2 = 0;
cout << "Input your first Multiple: " << endl;
cin >> Multiple1;
cout << "Your First Multiple is: " << Multiple1 << endl;
cout << "Input your second Multiple: " << endl;
cin >> Multiple2;
cout << "Your Second Multiple is: " << Multiple2 << endl;
for (int i = 1; i <= 100; i++)
{
if (i % Multiple1 == 0 && i % Multiple2 == 0)
cout << "FizzBuzz" << endl;
else
if (i % Multiple1 == 0)
cout << "Fizz" << endl;
else
if (i % Multiple2 == 0)
cout << "Buzz" << endl;
else cout << i << endl;
}
{
cout << "Restart? (y/n) ";
cin >> again;
}
system("pause");
return 0;
}
}
Thank you.
This is my first project and I am completely new to coding so I am not sure what to do.

Answer 1

Your return 0 is misplaced, it should be outside the while loop.
And you shouldn't put a bracket {} around your cin >> again.
{ // this bracket doesn't needed
cout << "Restart? (y/n) ";
cin >> again;
}
Just use bracket when it needed e.g. in for, if, function, etc. It will not make a compile error. But I think it makes you misread and think the while loop was closed.

#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main()
{
int Multiple1 = 0;
int Multiple2 = 0;
char again = 'Y';
while (again == 'y' || again == 'Y')
{
int Multiple1 = 0;
int Multiple2 = 0;
cout << "Input your first Multiple: " << endl;
cin >> Multiple1;
cout << "Your First Multiple is: " << Multiple1 << endl;
cout << "Input your second Multiple: " << endl;
cin >> Multiple2;
cout << "Your Second Multiple is: " << Multiple2 << endl;
for (int i = 1; i <= 100; i++)
{
if (i % Multiple1 == 0 && i % Multiple2 == 0)
cout << "FizzBuzz" << endl;
else
if (i % Multiple1 == 0)
cout << "Fizz" << endl;
else
if (i % Multiple2 == 0)
cout << "Buzz" << endl;
else cout << i << endl;
}
{ //This bracket doesn't need.
cout << "Restart? (y/n) ";
cin >> again;
continue;
} // This bracket doesn't need.
system("pause");
return 0;
}
}
