实现一个函数，打印乘法口诀表，口诀表的行数和列数自己指定， 输入9，输出9*9口诀表，输出12，输出12*12的乘法口诀表。

#define _CRT_SECURE_NO_WARNINGS 1
#include "stdio.h"
void print(int line)
{
         inti = 0;
         for(i = 1; i <= line; i++)
         {
                   intj = 0;
                   for(j = 1; j <= i; j++)
                   {
                            printf("%d* %d = %2d", i, j, i * j);
                   }
                   printf("\n");
         }
}
int main()
{
         intline = 0;
         scanf("%d",&line);
         print(line);
system("pause");
         return0;
 
}
