求15的阶乘(15!)的程序可以通过多种编程语言实现。以下是几种不同编程语言的示例代码:
1. Python
```python
import math
计算15的阶乘
factorial_15 = math.factorial(15)
print("15! =", factorial_15)
```
2. Bash
```bash
!/bin/bash
计算15的阶乘
sum=1
for i in {1..15}; do
sum=$(($sum * $i))
done
echo "15! = $sum"
```
3. C++
```cpp
include
int main() {
int result = 1;
for (int i = 1; i <= 15; ++i) {
result *= i;
}
std::cout << "15! = " << result << std::endl;
return 0;
}
```
4. Java
```java
public class Factorial15 {
public static void main(String[] args) {
int result = 1;
for (int i = 1; i <= 15; ++i) {
result *= i;
}
System.out.println("15! = " + result);
}
}
```
5. JavaScript
```javascript
// 计算15的阶乘
function factorial15() {
let result = 1;
for (let i = 1; i <= 15; i++) {
result *= i;
}
return result;
}
console.log("15! =", factorial15());
```
这些示例代码分别使用Python、Bash、C++、Java和JavaScript编程语言计算15的阶乘,并输出结果。你可以选择适合你的编程语言来实现相同的功能。
