Finding Factorial in C language.

Hi,

I am working on a program that asks a user to enter a # between 1 to 50 and finds the factorial of that. It uses recursive function to find it.

Here is what I got so far:

Code:

include <iostream>

using namespace std;

//function prototypes

int getNum();
int fact(int);
void printResult(int, int);


int main()
{
int num;
int ans;

num = getNum();
ans = fact(num);
printResult(num, ans);

cout << endl << endl;
}
int getNum()
{
	int num;
	cout << "\nEnter a number:";
	cin >> num;
	return num;
}
int fact(int num)
{
	
	if (num == 0)
		return 1;
	else 
		return num * fact(num - 1);
	
}
void printResults(int num, int ans)
{
	cout <<"\nfactorial of" << num << "is : " << ans;
	
}

Its not working, can some please help me solve this problem.

Thanks

Considering that you aren't writing C, you have just failed your class.


Quzah.

If you want to hang on to this for your C++ class, then you should note that 50! does not fit in an int datatype. Either restrict the domain (a lot) further, or use a different data type.
