C语言

```c

include

int main() {

int i, f = 1, s = 0;

for (i = 1; i <= 9; i += 2) {

b = b * i;

s = s + b;

}

printf("1!+3!+5!+7!+9!=%d\n", s);

return 0;

}

```

Python

```python

def factorial_sum(n):

s = 0

for i in range(1, 2*n+1, 2):

s += i

return s

n = 9

print(factorial_sum(n))

```

JavaScript

```javascript

function factorialSum(n) {

let s = 0;

for (let i = 1; i <= 2*n; i += 2) {

s += i;

}

return s;

}

let n = 9;

console.log(factorialSum(n));

```

Java

```java

public class FactorialSum {

public static void main(String[] args) {

int n = 9;

int sum = 0;

for (int i = 1; i <= 2*n; i += 2) {

sum += i;

}

System.out.println("1!+3!+5!+7!+9!=" + sum);

}

}

```

C++

```cpp

include

int main() {

int n = 9;

int sum = 0;

for (int i = 1; i <= 2*n; i += 2) {

sum += i;

}

std::cout << "1!+3!+5!+7!+9!=" << sum << std::endl;

return 0;

}

```

这些代码示例分别使用C语言、Python、JavaScript和C++计算1! + 3! + 5! + 7! + 9!的和。你可以选择适合你的编程语言进行尝试。
