Why does it generate a random number in the sequence of iterations when outputting the buble sort algorithm?

Question

void bublesort(double array[n]){
for(int i = 0; i < n; i++) {
for(int j = 1; j < n-i+1;j++)
if (array[j-1] > array[j])
{
double temp = array[j-1];
array[j-1] = array[j];
array[j] = temp;
}
cout << "Iteracioni " << i+1 << endl;
for(int i = 0; i <= n; i++)
cout << array[i] << endl;
}

Answer 1

In your last for loop, the condition must not be including n. Use less than instead of less than or equal to. That's probably gonna solve it. A question pops up in my mind here! Don't you get index out of range error? 🤔 try this one below 👇
for(int i = 0; i < n; i++)
