程序代码：

#include <iostream>
using namespace std;

int main()
{
    const int num = 8;
    int i, j;
    int a[num][num];

    for (i=0; i<num; i++)
    {
        for (j=0; j<=i; j++)
        {
            if (j==0 || j==i)
            {
                a[i][j] = 1;
            }
            else
            {
                a[i][j] = a[i-1][j-1] + a[i-1][j];
            }
            cout<<a[i][j]<<"\t";
        }
        cout<<"\n\n";
    }

    return 0;
