C++解答

#include <iostream>
using namespace std;

int main()
{	
	int data[10] = {0};
	

	int cc;
	for (int i=0; i<10;i++)
	{
		data[i] = 1;
		for (int k = i-1; k >=1; k--)
		{
			data[k] = data[k]+data[k-1];
		}

		cc = 0;
		for (int j =0; j<=i; j++)
		{
			if (cc==0)
				cout<<data[j];
			else
				cout<<" " <<data[j];
			cc++;
		}
		cout<<endl;
