C++ 初学阶段-九九乘法口诀表（九九乘法c++语言程序）

学程序重要的思维，直接开始都会背诵的九九乘法口诀表

#include <iostream>

using namespace std;

int main()

{

//利用循环定义Y轴（纵向）

for(int y = 1; y < 10; y++)

{

//利用循环定义x轴（横向，注意横向是变化长度）

for(int x = 1; x <= y; x++)

{

// 打印输出九九乘法口诀表

cout << x << " * " << y << " = " << x*y << " ";

}

// 每个横向输出结束后注意换行到下一纵向

cout << "\n";

}

//按任意键退出

system("pause");

return 0;

}

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
