Write a C++ program to roll 3 dice, show the values of these dice, and show the total

Please I need help with this.
Write a C++ program to roll 3 dice, show the values of these dice, and show the total value of these dice.?

I actually did this but I am very sure it is wrong.

 #include <iostream>
   #include <cstdlib>
   #include <time.h>
    
  using namespace std;
    
 int rollDice();
   
 int main(int argc, char* argv)
  {
      int numRolls;
       int arrRolls[6];
       int dieRoll;
  
       srand((unsigned)time(0));
   
      cout << "How many times would you like to roll the dice?" << endl;
       cin >> numRolls;
    
     for (int k = 0; k < 6; k++)
      {
           arrRolls[k] = 0;
       }
   
       for (int i = 1; i <= numRolls; i++)
      {
          dieRoll = rollDice();
         cout << "Die Roll " << i << ": " << dieRoll << endl;
          arrRolls[dieRoll - 1]++;
      }
    
     for (int j = 0; j < 6; j++)
     {
           cout << "The number " << j + 1 << " was rolled " << arrRolls[j] << " times." << endl;
       }
 }
    
   int rollDice()
   {
       int result;
    
       result = (rand() % 6) + 1;
    
       return result;
   }

hmmm...think that the three dice should be rolled simultaneously.
1. So you want to generate three random integers with values between 1 and 6 inclusive.
2. Output required is the value of each die and the sum of the three dice.
Can you do 1.? (not sure I can) but 2. should then be pretty simple.
BTW what happened when you compiled and ran your program ... any warnings or errors?

Line 42

result = (rand() % 6) + 1;

Is a very poor way to obtain a random result between 1 - 6 because the low bits of the standard library random number generator are often not very random but this relies solely on the low bits.

This was the ouput when I compiled it. That doesn't look like what we were told to do. Help me with the second part, I would try to figure out the first part.

How many times would you like to roll the dice?
3
Die Roll 1: 1
Die Roll 2: 2
Die Roll 3: 1
The number 1 was rolled 2 times.
The number 2 was rolled 1 times.
The number 3 was rolled 0 times.
The number 4 was rolled 0 times.
The number 5 was rolled 0 times.
The number 6 was rolled 0 times.
Press any key to continue . . .

Okay!Thank you. I have read it. I will try to do it over again and see how it comes out.
