Range of data type "unsigned int"

[Lauro]

Well,

First of all, I'm a newbie user.
I need your help!!!
I use a Borland C++ compiler version 3.0. So the range of the unsigned int data type is from 0 up to 65,000. Well,
I tried store the value 40,030 into an variable that it used this data type but, when I runned the program I received the following value: -25,216.
What's happened??
See the source code below:

#include <stdio.h>
#include <conio.h>

unsigned int fatorial(int N);

void main(void)
{
int ValInt;
unsigned int ProdFator;
clrscr();
printf(&quot;Calcule fatorial de &quot;
scanf(&quot;%d&quot;,&ValInt);
ProdFator = fatorial(ValInt);
printf(&quot;%d! ‚ igual a %d&quot;, ValInt, ProdFator);
}

unsigned int fatorial(int N)
{
int contador;
unsigned int ValFator = 1;

for(contador = 1; contador <= N; ++contador) ValFator = contador * ValFator;
return(ValFator);
}

Hello,
this is normal. You are displaying a signed decimal value (%d) instead of an unsigned decimal value (%u).
Change this
printf(&quot;%d! ‚ igual a %d&quot;, ValInt, ProdFator);
into
printf(&quot;%d! ‚ igual a %u&quot;, ValInt, ProdFator);
