recursive factorial prblm

Could anyone help me debug this

// recursive factorial prblm 4 pg 290 c++ primer plus

#include <iostream>
using namespace std;

float factorial(int n);

int main()
{
int n;
float fact;

cout << "Enter an integer:";
cin >> n;

fact=factorial(n);

cout << "The factorial is:" << fact << endl;

}

float factorial(int n)
{
float temp
if (n>0)
temp= n*factorial(n-1);

return temp;
}

hmmm looks ok what errors are you getting.

what about the 'return 0' in main.. is that the error

and the ; for float temp

float factorial(int n)
{
float temp
if (n>0)
temp= n*factorial(n-1);

No ; after float temp

Does no one read the error messages? It seems like people stop reading after they see 'Error' and come ask us to debug it without even trying. You had a syntax error and a warning about main returning a value.

Code:

---

#include <iostream>
using namespace std;

float factorial(int n);

int main()
{
  int n;
  float fact;
  cout << "Enter an integer:";
  cin >> n;
  fact=factorial(n);
  cout << "The factorial is:" << fact << endl;
  return 0;
}

float factorial(int n)
{
  float temp;
  if (n>0)
    temp= n*factorial(n-1);
  return temp;
}

-Prelude

thanks for all the help, being a newbe i didnt spot the semi colons though i stared at my source code wondering what was wrong. From now on thats the first thing ill check

thanks again

Not to be a little hasty, but doesn't your compiler give you any clues on what is wrong?

I agree with Prelude, a simple once over the error messages and even a run through with a debugger (something that nobody here uses for some reason) will solve 85% of the problems posted on the board.
