(for)(do)(while) loops using Xcode

[brasile]

Write a C++ program that will input from the user a positive number n and find its factorial. Don’t forget to validate the input. The factorial of a positive integer n (denoted by n!) is defines as the product of the integers from 1 to n. n! = 1* 2 * 3 * ... * (n - 1) * n
You should allow the user to continue working with your program for additional data sets.


Sample output:

Please enter a number: 5
5! = 120
Would you like to continue (Y/N)?Y
Please enter a number: 3
3! = 6

Would you like to continue (Y/N)?N
Good Bye!!


I have a basic idea of what to do but I'm missing a step somewhere and I would like to learn what I am doing wrong if someone can post either steps or a code so i can base off it would be helpful. my code for what i think I'm doing is as follows


#include <iostream>
using namespace std;
int main()
{
int i=1;
int n;
char ans;
int factorial;


cout<< "Would you like to enter a number ?(Y/N)"<< endl;
cin>>ans;


cout<< "Please enter a number"<< endl;
cin>> n;
while (i<=n) {
do {
factorial *= i;
i++;
cout<<n<<"!="<<factorial<< endl;
cout<< "Would you like to enter a number ?(Y/N)"<< endl;
cin>>ans;
} while ((ans =='y')||(ans =='Y'));

}




return 0;
}
still learning everything so please let me know if completely botched something

Why don't you post your code, and we can help point out where you are going wrong.
