Simplify.
Use a case statement for handling each side of the die.
if you insist on if-then, then use if-elseif-else-
Shouldn't you return the value you rolled?
Or why go through all that pain. Use a table!
char *Dice[] =
{
"*********\n" \
"* *\n" \
"* * *\n" \
"* *\n" \
"*********\n",
"*********\n" \
"* * *\n" \
"* *\n" \
"* * *\n" \
"*********\n",
"*********\n" \
"* * *\n" \
"* * *\n" \
"* * *\n" \
"*********\n",
"*********\n" \
"* * * *\n" \
"* *\n" \
"* * * *\n" \
"*********\n",
"*********\n" \
"* * * *\n" \
"* * *\n" \
"* * * *\n" \
"*********\n",
"*********\n" \
"* * * *\n" \
"* * * *\n" \
"* * * *\n" \
"*********\n"
};
n = rnd() % 6;
cout << Dice[ n ];

Thanks for the suggestions :) Never thought about it that way :)

your random dice aren't random.

Correct me if I'm wrong, but wouldn't this be pseudorandom and return the exact same series every time it's run? The way I was taught was to use a seed like this....
#include <ctime>
int seed = static_cast<int>(time(0));
srand(seed);
int randomNumber = minimum + rand() % (maximum - minimum + 1);

necrolin it's just:
srand(time(NULL));/*only once*/
int var = rand()%max_requested_value; Be a part of the DaniWeb community
