Description

  九九乘法表是数学学习的基础，今天我们就来看看乘法表的相关问题。《九九乘法歌诀》，又常称为“小九九”,如下图所示。你的任务是写一个程序，对于给定的一个正整数 n ，输出“九九乘法表”的前 n 行。例如，输入 n 为 9，你的程序的输出将为下图： 

---

Input

Comprising a plurality of sets of test data input, an EOF end. Each test contains only a positive integer n (0 <n <10).

---

Output

For each test case, the output map "multiplication table" shown in the first n rows.

---

Sample
Input

2
3

---

Output

11=1
12=2 22=4
11=1
12=2 22=4
13=3 23=6 3*3=9

---

Hint

You must use a for loop, if your code appears for example

if(n == 1) printf(“1*1=1\n”);

if(n == 2) printf(“11=1\n12=2 2*2=4\n”);

Or similar statements, this question does not score points.

The main question is to find the relationship between the line and two multipliers

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int n,i,j;
    while(scanf("%d",&n)!=EOF)
    {
        for(i=1; i<=n; i++)

        {
            for(j=1; j<=i; j++)
            {
                if(j==1)
                {
                    printf("%d*%d=%d",j,i,j*i); 
      //第二个乘数就是行数，第一个乘数是由“1”递加到“行数”，最后是结果；

                }
                if(j!=1)
                    printf(" %d*%d=%d",j,i,j*i);

            }
            printf("\n");


        }

    }

    return 0;
}
