乘法口诀表用while实现
时间: 2023-05-18 07:03:02 浏览: 51
以下是使用 while 循环实现乘法口诀表的代码:
```python
i = 1
while i <= 9:
j = 1
while j <= i:
print(f"{j} * {i} = {i*j}", end="\t")
j += 1
print()
i += 1
```
这段代码会输出乘法口诀表,每行一个数字,格式为 "a * b = c",其中 a 和 b 分别从 1 到 9,c 为它们的积。

乘法口诀表用Java的while实现
可以使用以下代码实现乘法口诀表的Java while循环:
```
int i = 1;
while (i <= 9) {
int j = 1;
while (j <= i) {
System.out.print(j + " * " + i + " = " + (i*j) + "\t");
j++;
}
System.out.println();
i++;
}
```
这段代码会输出以下结果:
```
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
```
Python语言 用while循环输出九九乘法口诀表
可以使用两个嵌套的 while 循环来实现九九乘法口诀表的输出。代码如下:
```python
i = 1
while i <= 9:
j = 1
while j <= i:
print(j, "*", i, "=", i * j, end="\t")
j += 1
print("\n")
i += 1
```
运行结果如下:
```
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
```
