Flogging factorial

I have decided to post atleast once per day, so for want of a better topic, I am going to write a simple factorial program in C and flog it to death. Well here we go, let me start with a childish

#include
int main(void) 
{ 
       int number, i = 1,result=1; 
       printf("\nEnter number: "); 
       scanf("%d",&number); 
       for(i=1;i<=number;i++) result = result*i; 
       printf("%d! = %d",number,result); 
       return 0; 
} 
Simple, but if i want to use gprof to profile, i need to put the code for factorial in a separate function.

So, 

#include
int factorial(int n) 
{ 
    int i=1, result = 1; 
    for(i=1;i<=n;i++)result = result*i; 
    return result; 
} 

int main(void) 
{ 
    int number; 
    printf("\nEnter number: "); 
    scanf("%d",&number); 
    printf("%d! = %d",number,factorial(number)); 
    return 0; 
} 

And compile using cc -o flogFact flogFactorial.c -g -pg 

Well, after running  ./flogFact I get the gmon.out 

Now let me run gprof flogFact 
judge@boss:~/delete$ gprof flogFact -b 

Flat profile: Each sample counts as 0.01 seconds. 
no time accumulated 

% cumulative self                 self total 
time    seconds    seconds    calls    Ts/call    Ts/call   name 
0.00     0.00          0.00           1           0.00       0.00       factorial 

Call graph granularity: each sample hit covers 4 byte(s) 
no time propagated 

index % time     self     children       called         name 
                           0.00     0.00              1/1              main [5] 
[1]            0.0      0.00     0.00              1                 factorial [1] ----------------------------------------------- 

Index by function name 

[1] factorial 

Shit, no useful info just as yet, grr.. some more stuff to do, but i'm off for lunch...
