Print a table of multiplication formulas that we know well!

一个很简单的打印！

int main()
{
    
    
	int i, j;
	for (i = 1; i<=9; i++)      //外循环改变乘数
	{
    
    
		for (j = 1; j <= i; j++)//内循环从1开始相乘，直到i
		{
    
    
			printf("%d*%d=%2d ", i, j, i*j);//注意格式，使最终打印对齐
		}
		printf("\n");
	}
	printf("\nGood job! \n");

	return 0;
}
