Arrays messed up C++ -

const int n = 5;  int person[] = {2, 3, 12, 5, 19}; int big = 0; int small = 100; int i;  (i = 0; <= n; i++) {     cout << "person[" << << "] ate: " << person[i] << endl;     //cin >> person[i];      (int j = i+1; j <= n; j++)     {         if (person[i] < person[j])         {             int tmp = person[i];             person[i] = person[j];             person[j] = tmp;         }     }             if (person[i]>big)         big=person[i];     if (person[i]<small)         small=person[i]; }     cout << "person[" << << "] ate pancakes: " << big << endl;     cout << "person[" << << "] ate least pancakes: " << small << endl;      cout << "sorted:" << endl;     (i = 0; < n; i++)     {         cout << "person[" << << "]: " << person[i] << endl;     }         system("pause"); 

output

where messed arrays keeps showing me 2 bubble sorting works. , other question how array index smallest value , array index highest value?

in c++ arrays zero 0 indexed. should change loops this:

for (i = 0; < n; i++)              ^^^ {     // code...     (int j = i+1; j < n; j++)                        ^^^     {         // code... 

because:

index    -> 0  1  2   3  4  person[] = {2, 3, 12, 5, 19}; 

in code value of i , j increment n 5. means trying access array named person's 5th index create array index out of bound error.
