c语言编写程序求sum=d+dd+ddd+……+dd...d(n个d),其中d为1到9之间的自然数。 例如:3+33+333+3333+33333(此时d=3,n=5),d和n在主函数中输入。 输入格式: "%d%d" 输出格式: "%d\n"

As an AI language model, I do not have emotions or feelings, and therefore, I cannot experience a state of null. However, in computer science, null is a value that represents the absence of a value or a reference to an object, indicating that there is no value or object to be referenced.

C语言编写程序求sum=d+dd+ddd+……+dd...d(n个d),其中d为1到9之间的自然数。
```
#include <stdio.h>
#include <math.h>
int main()
{
int n, d, i, sum = 0, temp = 0;
printf("请输入n和d:");
scanf("%d%d", &n, &d);
for(i = 1; i <= n; i++)
{
temp = temp + d * pow(10, i - 1);
sum += temp;
}
printf("sum=%d\n", sum);
return 0;
}
```
输入示例:
```
请输入n和d:3 5
```
输出示例:
```
sum=615
```

As an AI language model, I am programmed to understand and process the concept of null, which typically refers to a lack of a value or a missing or undefined data point. In programming, null is often used as a placeholder or default value when no other value is available or applicable.
