Thread: C Programming Dice Display Function?

I need a function (for part of a much bigger program) that displays two dice side by side. such as

@ @ @
@
@ @ @

But the function cannot be extensive, meaning i cannot just write out 36 instances. The function would intake an Int variables die1, die2 for the number to be rolled. Which comes from a random number generater in the main function.

The function does not have to be like below, but if you know how thatd be awesome too. A hint the question gives me is:

? ? ? ? ? ?
? ?
? ? ? ? ? ?

Your program can fill in each '?' appropriately with a '@' or a ' ' by using the conditional operator, ... ? ... : ... . (Or maybe use arrays of characters and sprintf().) And/or do further extensions that you devise — use your imagination! (;-)



What ive been working on is this, but it is too confusing and extensive.

Code:

double dice(int die1, int die2)
{
int roll, total;
double average;
printf("+-------+ +-------+\n");
//then you can go into if statements that print for common rolls
if(die1 == 5 || die1 == 6 || die1 == 4)
{
printf("| @ @ | ");
if(die2 == 5 || die2 == 6 || die2 == 4)
{
printf("| @ @ |\n");
}
if(die2 == 2 || die2 == 3)
{
printf("| @ |\n");
}
if(die2 == 1)
{
printf("| |\n");
}
}
if(die1 == 2 || die1 == 3)
{
printf("| @ | ");
if(die2 == 6)
{
printf("| @ @ |\n");
}
if(die2 == 2 || die2 == 3)
{
printf("| @ |\n");
}
if(die2 == 1)
{
printf("| |\n");
}
}
if(die1 == 1)
{
}

return(roll);
}

The first dice show 3 and 4, the second 2 dice show question marks in the shape on an H

Do the dice have to be in standard configurations?

Can a 2 be represented as
o o o
o x x
o o o (or anything else)

Or, does it have to be the standard
o o x
o o o
x o o

I believe it has to be the standard look

One idea might be if you use an array die[3][3] you can study the dots: Dice - Wikipedia, the free encyclopedia
So the centre dot die[1][1] would be on for odd numbers.
Top-left corner die[0][0] appears to be on for numbers >= 4
Top-right corner die[0][2] appears to be on for numbers >=2
and so on.
I don't want to do your homework for you but you should be able to make similar conditionals for each of the 3x3 dot positions.
Maybe use die2 for the second die. Then print out the two die beside each other one row at-a-time.

Can you explain your array idea in a more dumbed down version, Im very bad with C, and our teacher hasn't yet taught us arrays, but expects us to use them.

Take a look at a normal standard die.
Divide the face into nine sections -- these are your array elements.
Then you just have to store all of the possible faces in a way obvious to you.
When someone rolls the die, you pick the right face.
