[Dev-C++] die rolling problem

[PETER C. <pca...@cc...>]

Remarks by per are below..i attempted to set up a counter to count the number of times a die comes up and from that calculate the percentage. so far i get very small negative numbers...
am i going in the correct direction?

#include <iostream>
#include <ctime>
#include <cstdlib>
using namespace std;
int main()
{
    
    int rolls;
    cout << "how many times do you want to roll the die? ";     //how many times to roll die
    cin >> rolls;                                               //user input
    int faces[6] = {0};                                         //array for storage of faces of die. 
                                                                //used later to calculate percentage
    int face;                                                
    srand(time(0));                                             //user wants new random #'s generated each time 
    int face_per;
    
    int die[6] = {1,2,3,4,5,6};
        for(int i = 0; i < rolls; i++){
            face = rand();
            face = 1+ face%6;
        cout << "the die has rolled: " << face << endl;   
    }     
    
    int face_1;
    int face_1_occur;
    faces[0] = face_1;
    face_1_occur = 0;
    for(int i =0; i<rolls; i++){
        face_1_occur = face_1 + 1;                               //counter for face 1
    
    double prob_1 = face_1_occur * 100/rolls;
    cout << "the probability to roll a 1 is" << prob_1 << endl;
}   
     return 0;   
    }

1) You don't store an infinite number of dice values - no need to. Just 
emit the value for each throw on the fly. Then keep 6 counters - one for 
each of the 6 faces of the dice. 

2) Emit the 6 counters. Percentage is just # of occurences * 100 / total 
throws. 

3) If the values you put into an array are in range 1-6, of course the 
values stay in that range. However, normally when counting number of 
times you get a one, a two etc, you store that in an array with index 0 to 
5, since all arrays in C and C++ starts with index zero.
