Some one please help me I am getting CE.....
Code: Select all
#include<stdio.h>
int main()
{
long double fact,i,n,count;
while(scanf("%Lf",&n)==1)
{
fact=1;
count=1;
for(i=1;i<=n;i++)
{
fact=fact*i;
if(fact>6227020800)
{
count=0;
printf("Overflow!\n");
break;
}
}
if(count!=0)
{
if((fact/1000)<1)
{
printf("Underflow!\n");
}
else
{
printf("%.0Lf\n",fact);
}
}
}
return 0;
}

1/0 is not defined rather than infinite
the problem may have bad influence on the mathematical concept of the solver

I've read all posts in this topic.
I believe that I am doing right, but unfortunately I don't. I am getting WA.
Here is my code:
Code: Select all
#include "stdio.h"
unsigned long iter_factorial(int n) {
unsigned long accu = 1;
unsigned long i;
for(i = 1; i <= n; i++) {
accu *= i;
}
return accu;
}
int main() {
unsigned long x;
int a;
while( scanf("%d", &a) != EOF )
{
if( a <= 7 && a >= 0)
printf("Underflow!\n");
else if(a > 13)
printf("Overflow!\n");
else if(a < 0)
{
if( a / 2 * 2 == a)
printf("Underflow!\n");
else
printf("Overflow!\n");
}
else {
x = iter_factorial(a);
printf("%lu\n",x);
}
}
return 0;
}
Thank you..

I didn't checked your code. But i think you should use long long.

My factorial function calculates the factorials of numbers between 8 and 13 [including them]. But I was getting WA.
I replaced the factorial function with the precalculated values. ( if (x == 8 ) printf("...") .....)
And I got AC.
