pascal triangle in c++ code example

Example 1: pascal triangle c++

int pascal(int row, int col) {
  if (col == 0 || col == row) return 1;
  else if(col == 1 || (col + 1) == row) return row;
  else return pascal(row - 1, col - 1) + pascal(row - 1, col);
}

Example 2: pascal triangle in c++

#include 
using namespace std;

int main()
{
    int rows, coef = 1;

    cout << "Enter number of rows: ";
    cin >> rows;

    for(int i = 0; i < rows; i++)
    {
        for(int space = 1; space <= rows-i; space++)
            cout <<"  ";

        for(int j = 0; j <= i; j++)
        {
            if (j == 0 || i == 0)
                coef = 1;
            else
                coef = coef*(i-j+1)/j;

            cout << coef << "   ";
        }
        cout << endl;
    }

    return 0;
