将自己的名字全拼,学号用E命令显示在dos窗口中间位置
时间: 2024-05-09 09:20:41 浏览: 114
1. 打开cmd窗口
2. 输入以下命令:
```
mode con cols=80 lines=25
```
这将把cmd窗口的列数设置为80,行数设置为25。
3. 输入以下命令,将自己的名字全拼和学号显示在窗口中间位置:
```
@echo off
set name=your_full_name
set id=your_student_id
set /a middle=(80-%len%) / 2
cls
for /l %%a in (1,1,%middle%) do (echo.)
echo %name%
echo %id%
pause>nul
```
将上述命令中的your_full_name和your_student_id替换为自己的名字全拼和学号。执行上述命令后,自己的名字和学号将会在cmd窗口的中央位置显示。

Sorry, as an AI language model, I don't have a student ID and don't have the authority to execute commands on your computer. However, I can provide some general guidance on debugging and displaying text in the center of a DOSBox window.
To debug your code, you can use a debugger tool like GDB or a debug mode in your IDE. Set breakpoints and step through your code to identify any errors or unexpected behavior.
To display text in the center of a DOSBox window, you can use the following steps:
1. Use the MODE command to set the screen size and number of lines. For example, to set the screen size to 80 columns and 25 lines, use the command "MODE CON: COLS=80 LINES=25".
2. Use the ECHO command to display your name and student ID. For example, to display your name "John Smith" and student ID "1234567", use the command "ECHO John Smith, 1234567".
3. To center the text horizontally, you can use the SET /P command to read a null input and set the cursor position to the middle of the screen. For example, use the command "SET /P= " to set the cursor position to the middle of the screen.
4. To center the text vertically, you can use the CHOICE command to wait for the user to press a key. For example, use the command "CHOICE /C:ABCDEFGHIJKLMNOPQRSTUVWXYZ /N /T:5,5" to wait for 5 seconds at the center of the screen.
Note that these commands may vary depending on your DOSBox version and configuration. Also, be careful when executing commands in the DOSBox environment as they may affect your system or cause unintended consequences.
上电时,LCD1602显示屏第一行任意位置显示自己姓名的拼音(全拼) 按键K1按下奇数次时,在第二行任意位置显示自己学号的最后一个数字,按下偶数次时,显示数字变为0.,单片机,C语言程序
要实现在上电时LCD1602显示屏的第一行显示姓名拼音并响应按键K1的功能,你需要遵循以下步骤编写一个基于单片机(例如Arduino或μC)的C语言程序:
1. **初始化硬件**:
- 初始化LCD1602模块,设置起始地址、数据线、控制线等。
- 对按键K1进行输入捕获,一般通过中断或者定时器的方式检测按键状态。
2. **姓名拼音显示**:
- 定义字符串数组存储姓名的拼音,确保已转换为全拼格式。
- 使用LCD的指令集在第一行指定的位置写入姓名拼音。
3. **处理按键状态**:
- 读取按键K1的状态,并判断其次数是否为奇数或偶数。
- 如果是奇数次,从用户学号中取出最后一个数字并显示到第二行。
- 如果是偶数次,将第二行显示的内容清零。
4. **更新显示**:
- 在每次按键事件后,更新液晶屏上的内容。
5. **主循环和异常处理**:
- 在无限循环中等待按键触发事件,同时检查是否有其他错误或特殊情况。
```c
#include <LiquidCrystal.h>
// LCD1602配置
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
// 假设姓名和学号为全局变量
char namePinyin[] = "YourNamePinyin";
int studentID;
void setup() {
// LCD初始化
lcd.begin(16, 2);
// 其他硬件初始化
}
void loop() {
int k1State = digitalRead(K1_PIN);
if (k1State == HIGH) { // 检测按键按下
if (digitalRead(K1_PIN) % 2 == 1) { // 奇数次按下
lcd.setCursor(0, 1);
lcd.print(studentID % 10);
} else { // 偶数次按下
lcd.setCursor(0, 1);
lcd.print(0);
}
}
lcd.setCursor(0, 0);
lcd.print(namePinyin);
delay(100); // 短暂延时避免频繁刷新
}
```
注意:这个示例假设你已经有了LCD1602的硬件连接以及一个名为`K1_PIN`的按键引脚。实际编程时需要替换为相应的硬件配置。另外,姓名拼音的全拼应预先存入`namePinyin`数组中,学号则需在程序运行前赋值给`studentID`。
