ok so here it is, Im trying to make a dice roller/random number generator this is what i got so far

CODE

#include <iostream>
#include <stdlib>

using namespace std;

int main()
{
  int a = random ( 100 - 1 ) + 1,b = random ( 20 - 1 ) + 1,c = random ( 12 - 1 ) + 1,Q=0,d;
  while ( Q < 20 ) {
  Q++;
  cout<<"What type of dice do you want to roll d%, d20, or d12?\n";
  cin>> d;
  cin.ignore();
  if ( d == 12 ) {
  cout<< c;
    }
  else if ( d == 20 ) {
  cout<< b;
    }
  else ( d == 100 ) {
  cout<< a;
    }
  }
  cin.get();
}
  


i have been working on this for close to a week on and off, and i get a "statement missing ; in function main()" at line 20, and a warning that 'a' is assigned avalue that is never used in function main()

any help any body

ok so i got the else statement workingo on line 20 and the program works now. But it only gives out one value for each die type (i.e. 20 gives a value of 14). Do I need some type of algorithm or am I thinking too hard?

Your random function = too hard thinking =P
Space your code a little, that might help you understand more what's going on.
For the random function :
CODE

#include <time.h>
#include <iostream.h>

#define MAX 100
#define MIN 1
int main()
{
   int a;

   srand(time(NULL));
   a = (rand() % (MAX - MIN + 1)) + MIN;
  
    cout<<a;
    return 0;
}


Compile and run and you'll understand it.
This function is from the time.h header.

ok this is the reformed code that i got when applied your strategy
CODE

#include <time>
#include <iostream>

using namespace std;

int main()
{
  int a,b,c,d;

  srand(time(NULL));
  a = (rand() % ( 100 - 1 )) + 1;
  b = (rand() % ( 20 - 1 )) + 1;
  c = (rand() % ( 12 - 1 )) + 1;

  cout<<"What type of dice do you want to roll d%, d20, or d12?\n";
  cin>> d;
  cin.ignore();
  if ( d == 12 ) {
  cout<< c<<"\n";
    }
  else if ( d == 20 ) {
  cout<< b<<"\n";
    }
  else {
  cout<< a<<"\n";
    }
}
  

but i guess the problem in having it in a while loop, I have to run the program again once i need a new roll, I'm thinking its because once it runs it once the same data set is used when finding another roll in the same instance of the program. Is there possibly a way to refresh the proposed data set?

By the way thank you
