can someone help me with this problem(factorial)
everything is working fine but when I enter a negative number the program crashes somewhere....but n can be any non-negative number
Here is da code

#include <iostream>
#include <string>

using namespace std;

int fact(int n){
if (n==0)
return 1;

return fact(n-1)*n;
int main()
int number;
char response;


cout<<"Enter number: ";
cout<<"factorial: "<<fact(number)<<endl;

cout<<"Do you want to continue: ";
cout<<"(Press Y/N)"<<endl;

}while((response=='y') || (response=='Y'));
return 0;

The formula for finding a factorialis:
If you have a negative number e.g -1, what would be the factorial?
-1(-2)(-3)(-4)(-5)(-6)..... it goes on to infinity.. That is why your program crashes.i.e if n is negative, there is no way n-1 can be equal to 1.

Please,if this helped, mark your thread as solved and add to my reputation points. Thanks!!

ofcourse it wil crash because it is getting into an infinite loop because its not reaching the final condition.

make your condition from if(n==0) to if(n<1) in the factorial function
