Code won't display output.

[marsupial23]

So I'm working on this homework problem where I have to "roll two six-sided die" and allow the "user" to enter the number of times the dice is rolled and then display the results in a table format somewhat like this:

Sum Total Rolls
2 2
3 5
4 6
... etc.

The problem I'm having is that once the "user" enters the number of rolls, the table part won't display. Pointers?

#include <iostream>
#include <stdlib.h>
#include <ctime>
#include <iomanip>
using namespace std;

int main( )
{

unsigned long int mySum[12]={0},die_score[11]={0};
int die1, die2, sum, X;

srand(time(0));

cout << "Please enter number of times for dice to be rolled: " ;
cin >> X ;

  for(int count=X;++X;)
  {
  die1=1+rand()%6;
  die2=1+rand()%6;
  ++mySum[die1+die2];
 }

  cout<<"Sum"<<setw(8)<<"Total Rolls" << endl;

 for(int j=2;j<13;++j)
 cout<<j<<setw(8)<<mySum[j]<<endl; 
}

You have an infinte loop in 19

How would I get rid of that?

#include <iostream>
#include <stdlib.h>
#include <ctime>
#include <iomanip>
using namespace std;

int main( ) {

    unsigned long int mySum[12],die_score[11]; // Why die_score. You don't ever use it

    int die1, die2, sum, X;

    srand(time(0));

    cout << "Please enter number of times for dice to be rolled: " ;
    cin >> X ;  // What happens if operator enters 20

      for(int count=0; count < X; count++) {
        die1 += rand()%6;
        die2 += rand()%6;
        mySum[count] = die1 + die2;
        }

      cout << "Sum" << setw(8) << "Total Rolls" << endl;

     for(int j =2 ;j < 13; ++j) // Why j=2
        cout << j << setw(8) << mySum[j] << endl;
        
    return 0;  // main should always return a value 
    }

This still doesn't work right, but I've commented the problem areas. It doesn't hang up now

The die score was something one of my classmates told me to put in. I got rid of it as you suggested. Changed mySum to a larger number, working fine now if I enter 20. :)

Thanks so much!

Could it be, this is what you were trying to do?

#include <iostream>
#include <stdlib.h>
#include <ctime>
#include <iomanip>

using namespace std;

int main( ) {

    unsigned long int mySum = 0, count;

    int die1, die2, X;
   
    die1 = die2 = 0;
    srand(time(0));

    cout << "Please enter number of times for dice to be rolled: " ;
    cin >> X;
    
      for(count = 0; count < X; count++) {
        cout << setw (5) << count + 1;
        die1 = rand() % 6 + 1;
        cout << setw (8) << die1;
        die2 = rand() % 6 + 1;
        cout << " +" << setw (2) << die2;
        cout << "  =" << setw (4) << die1 + die2 << "\n";
        mySum += die1 + die2;        
        }

    cout << "\n    Grand Total = " << mySum << endl;
    return 0;
    }
