代码:

```c

include

int main() {

int a, b, c, i = 0;

for (a = 1; a <= 5; a++)

for (b = 1; b <= 5; b++)

for (c = 1; c <= 5; c++)

if (a != b && a != c && c != b)

i++;

printf("A,B,C三人所选书号分别为:\n");

for (a = 1; a <= 5; a++)

for (b = 1; b <= 5; b++)

for (c = 1; c <= 5; c++)

if (a != b && a != c && c != b)

```cpp

include

using namespace std;

int main() {

long long I, bonus;

cout << "请输入当月利润I(万元): ";

cin >> I;

if (I <= 10)

bonus = I * 0.1;

else if (I <= 20)

bonus = 10 + (I - 10) * 0.075;

else if (I <= 40)

bonus = 30 + (I - 20) * 0.05;

else if (I <= 60)

bonus = 50 + (I - 40) * 0.03;

else if (I <= 100)

bonus = 70 + (I - 60) * 0.015;

else

bonus = 100 + (I - 100) * 0.01;

cout << "应发放奖金总数为: " << bonus << "万元" << endl;

return 0;

}

```

这些示例涵盖了从简单的Hello World脚本到复杂的奖金提成计算程序,帮助你在电脑上进行编程实践。建议从简单的示例开始,逐步掌握编程的基本概念和技巧,然后逐步尝试更复杂的项目。
