Вводимое число не совпадает с отображаемым кодом, используя массив в структуре, почему?

Question

Я делаю код, где пользователи могут вводить числа, которые будут храниться в массиве, который находится внутри структуры.Однако иногда значение, которое я ввожу, не совпадает с тем, которое хранится / отображается.Эта проблема не очень последовательна.Например, когда я ввожу 10, он может отображаться как: 6384644, 6382852 или фактически 10.Я очень смущен этим, я пытался изменить тип данных массива, используя int, long и double, но безрезультатно.

#include <iostream>
#include <iomanip>

using namespace std;

int main () {
int n,x,totalAge = 0,maxAge = 0,avgAge = 0,maxGoals = 0,bestPlayer = 0, oldest = 0;

cout << "Input the number of players: ";
cin >> n;

cout << "Input the number of games: ";
cin >> x;

struct players {
    string name;
    string currTeam;
    int shirtn;
    int age;
    float height;
    float weight;
    int totalGoals;
    long goals[];
};

players goals[x];

players playerList[n];

for (int i = 0; i < n; i++) {
    cout << "Player " << (i+1) << endl;
    cout << "Input player's name: ";
    cin.ignore();
    getline (cin, playerList[i].name);
    cout << "Input player's current team: ";
    getline (cin, playerList[i].currTeam);

    cin >> playerList[i].height;
    cout << "Input player's weight (kg): ";
    cin >> playerList[i].weight;

    cout << endl;

    for (int a = 0; a < x; a++) {
        playerList[i].goals[a] = 0;
        playerList[i].totalGoals = 0;
    }

    for (int a = 0; a < x; a++) {
        cout << "Game " << (a+1) << "'s number of goals: ";
        cin >> playerList[i].goals[a];
        playerList[i].totalGoals += playerList[i].goals[a];
    }

    if (playerList[i].totalGoals > maxGoals) {
        maxGoals = playerList[i].totalGoals;
        bestPlayer = i;
    }

    if (playerList[i].age > maxAge) {
        maxAge = playerList[i].age;
        oldest = i;
    }

    totalAge += playerList[i].age;
    cout << endl;
}

cout << endl;

for (int i = 0; i < n; i++) {
    cout << playerList[i].name << endl;
    cout << "--------------------" << endl;
    cout << "Current team: " << playerList[i].currTeam << endl;
    cout << "Shirt Number: " << playerList[i].shirtn << endl;

    cout << "Height: " << playerList[i].height << " m" << endl;
    cout << "Weight: " << playerList[i].weight << " kg" << endl;

    cout << endl;

    for (int a = 0; a < x; a++) {
        cout << "Game " << (a+1) << "'s number of goals: " << playerList[i].goals[a] << endl;
    }

    cout << endl << endl;
}

avgAge = totalAge / n;

cout << "Average age of players: " << avgAge << endl;
cout << "Oldest Player: " << playerList[oldest].name << " (" << maxAge << ") ";
cout << "Player who got the most goals: " << playerList[bestPlayer].name << ", shirt number: " << playerList[bestPlayer].shirtn << ". With total goals of: " << playerList[bestPlayer].totalGoals << endl;

Исправленная версия вашего кода будет выглядеть так:

#include<string>
#include<iostream>
#include<vector>    //for vector
using namespace std;

struct players {
    string name;
    string currTeam;
    int shirtn;
    int age;
    float height;

    vector<long> goals;    //used vector instead of array
};

int main () {
    int N, X;
    int totalAge = 0, maxAge = 0, avgAge = 0, maxGoals = 0, bestPlayer = 0, oldest = 0;

    cout << "Input the number of players: ";
    cin >> N;

    cout << "Input the number of games: ";

    players player[X];

    for (int i = 0; i < N; i++) {
