+---- Thread: [C] Factorial function (/showthread.php?tid=12731)
[C] Factorial function - Commodore - 10-13-2010
Yes, another silly function. This time it finds the factorial of a number.
Usage:
Code:
factorial(number);Code:
Code:
long factorial(long x)
{
long factorial = x;
long i = 0;
for (i = (x - 1); i > 1; --i)
{
factorial = (factorial * i);
}
return factorial;
}Please be aware that any input number greater than 31 will not produce a useful result. This is because long integers cannot store numbers greater than the factorial of 31. Sorry.
RE: [C] Factorial function - RANA - 11-28-2010
a better program
Code:
#include <stdio.h>
int main()
{
int a;
int c=0;
int i;
printf("enter the number for finding fact");
scanf("%d",&a);
for(i=1;i<=a;i++)
{
c+=i;
printf("the factorial is:%d",c);
}
return 0;
}
