|
||
## 一、选择（20 分） 10道
|
||
|
||
函数可以没有返回值
|
||
|
||
实参形参必须完全一致
|
||
|
||
函数里不允许嵌套定义函数
|
||
|
||
## 二、填空（20 分）
|
||
|
||
1. 静态变量关键词\_\_\_\_，常态变量关键词\_\_\_\_
|
||
|
||
2. ```c
|
||
#include<stdio.h>
|
||
int main() {
|
||
int a = 3, b = 2;
|
||
float c = 3 * 5 / b;
|
||
printf("%.2f",c);
|
||
}
|
||
```
|
||
\_\_\_\_
|
||
|
||
3. `a = 9, b = 2`，`!(a * 2 % 4) && (c = 2) || (7 - 2 * b > 2)` 输出\_\_\_\_
|
||
|
||
4. `unsigned int` 取值多少 \_\_\_\_
|
||
|
||
5. `short arr[11];` 占用\_\_\_\_ bit(s)
|
||
|
||
## 三、判断输出（20 分）
|
||
|
||
1. ```c
|
||
#include<stdio.h>
|
||
int main() {
|
||
int row = 3, col = 4, i, j;
|
||
for(i = 0; i < row; i++) {
|
||
printf("#");
|
||
for(j = 0; j < col; j ++) {
|
||
if(i == j) break;
|
||
if(i == col - j) continue;
|
||
printf("*");
|
||
}
|
||
printf("\n");
|
||
}
|
||
return 0;
|
||
}
|
||
```
|
||
|
||
2. ```c
|
||
#include<stdio.h>
|
||
#define SQUARE(x) x*x
|
||
int main() {
|
||
int a = 5;
|
||
int b = SQUARE(a + 1);
|
||
printf("SQUARE(a+1):%d",b);
|
||
return 0;
|
||
}
|
||
```
|
||
|
||
## 四、手写代码（40 分）
|
||
|
||
|
||
1. 求五个数中的中位数
|
||
|
||
**Input**
|
||
|
||
> `5 2 4 3 1`
|
||
|
||
**Output**
|
||
|
||
> `3`
|
||
|
||
2. 求 `100~999` 的素数水仙花数，如果没有，输出`No Such Number.`
|
||
|
||
**Input**
|
||
|
||
> 无
|
||
|
||
**Output**
|
||
|
||
> `No Such Number.`
|
||
