factorial problem

write a program that evaluates the factorial of the integer 1 to 5. print result in tabular format.

Code:

---


#include <stdio.h>

long factorial(long number);
int main()
{
        int i,number;

        for (i=1;i<=5; i++) {
                printf("%2d!=%1d\n", i, factorial (number));
        }

        return 0;
}

long factorial(long number)
{
        if (number <=2) {
                return 1;
        else {
                return (number*factorial(number-1)); }
  }
}

---

Try
printf("%2d!=%li\n", i, factorial (i));

Well the logic given by our friend is right
use factorial(i)
i took the pain of compiling it in TurboC
here is the debugged program

Code:

---



#include <stdio.h>
#include<conio.h>
long factorial(long number);
int main()
{
        int i,number;

        for (i=1;i<=5; i++) {
                printf("%2d!=%1d\n", i, factorial (i));
        }

        getch();
        return 0;
}

long factorial(long number)
{
        if (number <=2)
        {
                return 1;
        }
        else
        {
                return (number*factorial(number-1));
        }
}

:D

thanks for the reply but all the number need to mutiply by 2 to be correct.

example from your program

6! = 60 but it suppose ot equal 120

> if (number <=2)
Probably because this 2 should be 1

Thanks everyone for the help, I finally got the program to run
