using namespace std;

int fact(int n)
{
if ( n >= 0)
{
if ( n==1 || n==0 )
{
return 1;
}
else
{
return n*fact(n-1);
}
}
else
{
cout << "Sorry Wrong No "<< endl ;
}

}

int main()
{
int a;
cout << "Enter The No ="<< endl ;
cin >> a;
cout << "Factorial ="<< fact(a) ;
return 0;
}

Answer 1

When you give a negative number as input it gives some sort of additional number like 4620160.This code will solve that problem.
you can use this code :
#include <iostream>
using namespace std;

int fact(int n)
{
if ( n >= 0)
{
if ( n==1 || n==0 )
{
return 1;
}
else
{
return n*fact(n-1);
}
}
else
{
// cout << "Sorry Wrong No "<< endl ;
return 0;
}

}

int main()
{
int a,b;
cout << "Enter The No ="<< endl ;
cin >> a;
b=fact(a);
if(b!=0)
cout << "Factorial ="<< b ;
else
cout<<"sorry wrong no";
return 0;
}

I just ran it and it worked fine. What compiler are you using?

Answer 3

what is the error you get while compiling ?
