Thread: FACTORIAL. Can you hel me about this

You can't add people on this. Even if you could, what would be the point, it's a forum, you just post messages.

Actually, for the double format you have to use %lf

But if you want to use %d then just change double fact to int fact

If you don't want to use void then use:

int main (int argc, char **argv)

im sorry again.!

Code:

#include <stdio.h>

int main(void) {
int n; /* The number of fibonacci numbers we will print */
int i; /* The index of fibonacci number to be printed next */ 
int current; /* The value of the (i)th fibonacci number */
int next; /* The value of the (i+1)th fibonacci number */
int twoaway; /* The value of the (i+2)th fibonacci number */

printf("How many Fibonacci numbers do you want to compute? ");
scanf("&#37;d", &n);
if (n<=0)
printf("The number should be positive.\n");
else {
printf("\n\n\tI \t Fibonacci(I) \n\t=====================\n");
next = current = 1;
for (i=1; i<=n; i++) {
printf("\t%d \t %d\n", i, current);
twoaway = current+next;
current = next;
next = twoaway;
}
}
return 0;
}

like this. is this corect?

I thought you were working on the factorial problem?

I don't even know how or what the fibonnaci series is, so I can't help you with that.

yea/ my code for Factorial is this

Code:

printf("\nFor X = %d\t\t", x);
		printf("X!(factorial) = %ld",fact(x));
		break;

is this correct.

is this corect should i use scanf?

It is correct providing your function

fact(x)

is also correct.

Post your whole code and not segments of it.

You are making this far more complicated than it actually is.

okay.

cant undertsand. haiyzzzzz help me please. the whole. coz its verry rush.

We can't help you if you don't post the code, you just posted some segment. Post your whole code.

Code:

 int n)
{
   if (n == 0)
  return 1;
   else
  return n * Factorial (n - 1);
}

}

The problem is i dont know where will i put the given number which is 10?

That's the factorial method.

So now in the main function, request the user to enter a number.
Scan that number, and send that number to the factorial function.
