## C multiplication table SDUT

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
1
2=2 22=4
1
1=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;
}
