구구단/조재화

데블스캠프 첫쨋날 구구단 코드.

처음 짠 코드

~cpp 
#include<iostream>
using namespace std;
int main()
{
	for(int i=1; i<10 ; i++)
	{
		for(int j=2; j<6; j++)
		{
			cout<<j<<"*"<<i<<"="<<j*i<<"\t";		
		}
		cout<<endl;
		;
	}
	
	cout<<endl;

	for(int d=1; d<10 ; d++)
	{
		for(int k=6; k<10; k++)
		{
			cout<<k<<"*"<<d<<"="<<k*d<<"\t";
		}
		cout<<endl;
	}
	return 0;
}
