下面是使用 while 循环输出九九乘法表的 Python 代码:
```
i = 1
while i <= 9:
j = 1
while j <= i:
print(j, '*', i, '=', i*j, end='\t')
j += 1
print()
i += 1
```
输出结果为:
```
1 * 1 = 1
1 * 2 = 2 2 * 2 = 4
1 * 3 = 3 2 * 3 = 6 3 * 3 = 9
1 * 4 = 4 2 * 4 = 8 3 * 4 = 12 4 * 4 = 16
1 * 5 = 5 2 * 5 = 10 3 * 5 = 15 4 * 5 = 20 5 * 5 = 25
1 * 6 = 6 2 * 6 = 12 3 * 6 = 18 4 * 6 = 24 5 * 6 = 30 6 * 6 = 36
1 * 7 = 7 2 * 7 = 14 3 * 7 = 21 4 * 7 = 28 5 * 7 = 35 6 * 7 = 42 7 * 7 = 49
1 * 8 = 8 2 * 8 = 16 3 * 8 = 24 4 * 8 = 32 5 * 8 = 40 6 * 8 = 48 7 * 8 = 56 8 * 8 = 64
1 * 9 = 9 2 * 9 = 18 3 * 9 = 27 4 * 9 = 36 5 * 9 = 45 6 * 9 = 54 7 * 9 = 63 8 * 9 = 72 9 * 9 = 81
```

使用while循环打印出九九乘法口诀表
以下是使用while循环打印出九九乘法口诀表的代码:
```
i = 1
while i <= 9:
j = 1
while j <= i:
print(j, "*", i, "=", i*j, end="\t")
j += 1
print()
i += 1
```
输出结果如下:
```
1 * 1 = 1
1 * 2 = 2 2 * 2 = 4
1 * 3 = 3 2 * 3 = 6 3 * 3 = 9
1 * 4 = 4 2 * 4 = 8 3 * 4 = 12 4 * 4 = 16
1 * 5 = 5 2 * 5 = 10 3 * 5 = 15 4 * 5 = 20 5 * 5 = 25
1 * 6 = 6 2 * 6 = 12 3 * 6 = 18 4 * 6 = 24 5 * 6 = 30 6 * 6 = 36
1 * 7 = 7 2 * 7 = 14 3 * 7 = 21 4 * 7 = 28 5 * 7 = 35 6 * 7 = 42 7 * 7 = 49
1 * 8 = 8 2 * 8 = 16 3 * 8 = 24 4 * 8 = 32 5 * 8 = 40 6 * 8 = 48 7 * 8 = 56 8 * 8 = 64
1 * 9 = 9 2 * 9 = 18 3 * 9 = 27 4 * 9 = 36 5 * 9 = 45 6 * 9 = 54 7 * 9 = 63 8 * 9 = 72 9 * 9 = 81
```
c语言代码while循环实现九九乘法表
以下是使用 C 语言 while 循环实现九九乘法表的代码:
```c
#include <stdio.h>
int main() {
int i = 1, j;
while (i <= 9) { // 控制行数
j = 1;
while (j <= i) { // 控制列数
printf("%d*%d=%d\t", j, i, i*j); // 输出乘法表中的一项
j++;
}
printf("\n"); // 输出一行后换行
i++;
}
return 0;
}
```
在这个程序中,外层的 while 循环控制行数,内层的 while 循环控制列数,并在每行输出完后换行。通过循环打印每一项乘法表中的值,即可完成九九乘法表的输出。
