Hi, I'm working on a homework assignment that asks me to roll two die a user given number of times, find the roll sums, and a few other things. I'm working on it one module at a time and I'm running into two big problems so far.

The first problem is that my int variable rolls changes to a number within the random number generator range of numbers after I run rolldie. I got around this by making a const equal to the user entered value of rolls just so that I could continue developing the program.

My second problem is that the values of the arrays resultsOne[] and resultsTwo[] are changed after running findsum(). I have no idea why this is happening and I even tried passing them as const, but that changed nothing. If anyone could point me in the right direction, I will be forever grateful!

We just started learning about passing arrays to functions, so there might be something big that I'm missing.

Thanks!

Code:
#include <iostream>
#include <cstdlib>

using namespace std;

void rolldie(int resultsOne[], int sizeOfresultsOne, int resultsTwo[], int sizeOfresultsTwo);
void findsum(int resultsOne[], int sizeOfresultsOne, int resultsTwo[], int sizeOfresultsTwo, int tossSums[], int sizeOftossSums);

int main()
{
    srand(time(NULL));
    int rolls = 0;
    int resultsOne[] = {};
    int resultsTwo[] = {};
    int tossSums[] = {};
    
    cout << "Enter number of tosses : ";
    cin >> rolls;
    const int roll = rolls;
    
    rolldie(resultsOne, rolls, resultsTwo, roll);
    cout << resultsOne[0] << endl;
    cout << resultsTwo[0] << endl << endl;    

    
    
    findsum(resultsOne, roll, resultsTwo, roll, tossSums, roll);

    cout << resultsOne[0] << endl;
    cout << resultsTwo[0];

            
    cin.sync();cin.ignore();
    return 0;
}

void rolldie(int resultsOne[], int sizeOfresultsOne, int resultsTwo[], int sizeOfresultsTwo)
{
   
     for(int i = 0; i < sizeOfresultsOne; i++)
     {
             resultsOne[i] = 1 + (rand() % 6);
             resultsTwo[i] = 1 + (rand() % 6);
     }

     for(int i = 0; i < sizeOfresultsTwo; i++)
     {
             resultsTwo[i] = 1 + (rand() % 6);
     }
}

void findsum(int resultsOne[], int sizeOfresultsOne, int resultsTwo[], int sizeOfresultsTwo, int tossSums[], int sizeOftossSums)
{
     cout << sizeOfresultsOne;
     
     for (int i = 0; i < sizeOfresultsOne; i++)
     {
         tossSums[i] = resultsOne[i] + resultsTwo[i];
     }
     
}
