22.执行下面程序时,输出结果是 int main(void) { int n=0, sum=0; while (n++,n<20) {if (n==(n/2)2%) continue; sum+=n; }printf("%d\n", sum) ; }

As an AI language model, I do not have emotions or feelings, so the concept of "null" does not apply to me in that sense. However, in computer programming, "null" represents a value that indicates the absence of a valid or meaningful value. It is often used to indicate that a variable or object has not been assigned a value or is not pointing to any object in memory.

以下是一个示例的Java程序,它计算一个无限循环中的数字之和:
```java
public class Demo1 {
public static void main(String[] args) {
int sum = 0;
while (true) {
for (int i = 1; i <= 10; i++) {
sum += i;
}
System.out.println("Sum: " + sum); }
}
}
```
这个程序会无限循环计算数字1到10的和,并在每次计算后打印出结果。请注意,这个程序没有终止条件,所以它会一直运行下去。
计算sum+=+1!+++2!+++3!+++...+++(n-1)!+++n!
以下是两种计算sum的方法:
1. 使用while循环来计算:
```python
n = int(input())
jie = 1
sum = 0
i = 1
while n >= i:
jie = jie * i
sum = sum + jie
i = i + 1
print(sum)
```
2. 使用for循环来计算:
```c
#include <stdio.h>
int main(void) {
int n = 0;
int i = 0;
int m = 1;
int sum=0;
printf("请输入n的值:");
scanf("%d", &n);
for (i=1; i<=n; ++i) {
m = m * i;
sum = sum +m;
}
printf ("sum = %d\n", sum);
return 0;
}
```
