int get_num(int a, int b, int c)
{
do
{
a = rand() % 10;
b = rand() % 10;
}
while (a == b);
do
c = rand() % 10;
while ((c == b) || (c==a));
return (a,b,c);
}

Try this:

#include <stdlib.h>

void get_num(int *a, int *b, int *c)
{
*a = rand() % 10;
do
{
*b = rand() % 10;
} while (*a == *b);
do
{
*c = rand() % 10;
} while ((*c == *b) || (*c==*a));
}

void main(void)
{
int a,b,c;
get_num(&a,&b,&c);
}

You must pass the address of the variables you want to return. I'm assuming
that the code should return 3 different numbers...

you can't return three values from a function. The compiler simply
returns the last one in a comma expression such as
return (a,b,c);

What you really want is this:
return a*100 + b*10 + c;

How do I make a two column chart. I need to keep track of players entry and
score. They have to guess the number the function chose until the computer
returns PPP. P = right digit right place, n = right number wrong place and
z = no number and all P's have to come first.
