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。
