C++输出99乘法口诀表.txt
为了输出九九乘法表,你可以使用嵌套的for循环来实现。以下是一段在C++中输出九九乘法表的代码:
```c++
#include <iostream>
int main() {
for (int i = 1; i <= 9; i++) {
for (int j = 1; j <= i; j++) {
std::cout << j << " * " << i << " = " << i * j << "\t";
}
std::cout << std::endl;
}
return 0;
}
```
这段代码首先使用外层的for循环控制行数,内层的for循环控制每行中的列数。在内层循环中,我们使用cout语句输出每个乘法表达式。
输出结果如下所示:
```
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
```
