AI Studio下C语言编程：一道简单的C语言作业题目_ai写c语言

简 介： 本文测试了在 AI Studio中进行C语言编程的过程。使用与 搭建AI Studio 中Python开发环境 同样的 “AIS” python文件，可以在Windows 与AI Studio之间进行C，Python文件传输、编写与运行。

§01 问题来源

---

  我是名大二的学生，这边有问题，有个简单编程作业想问下你，价钱好说 ：

一、题目要求

1、成绩处理

▲ 图1.1 作业要求

▲ 图1.2 作业要求

2、结果要求

  c语言，文件没啥要求，有程序代码就行了。

  类似于这种：

▲ 图1.1.3 作业结果要求

3、提交时间

  明天就要交了，麻烦你了

 

§02 作业分析

---

一、程序要求

1、编程语言

  编程语言是C语言。可以看到这是一个大学一年级 C语言课程的作业题目；

2、编程环境

  前面同学显示的变换环境为 VS。

  因此只要是基本的C语言，他都可以进行调试。

3、程序输入、输出

（1）程序输入

  程序中没有给出学生的成绩表格的要求。因此可以采用最简单的 CSV 格式来表示学生的成绩。

• 每一行表示一个学生的信息。有两个字段：学号，成绩;
• 学号采用字符串：“202109nnn”，其中nnn从 101 ~ 299，表示由199 位同学；
• 成绩采用浮点数： nn.m： 采用平均值为85，方差为30的正态分布；

（2）程序的输出

  可以看到只需要屏幕输出即可。

二、产生学生成绩单CSV文件

  使用AI Studio的终端环境，通过Python语言产生。由于这只是用于测试主程序，所以使用Python语言产生。

1、Python代码

  本文测试了在 AI Studio中进行C语言编程的过程。使用与 搭建AI Studio 中Python开发环境 同样的 “AIS” python文件，可以在Windows 与AI Studio之间进行C，Python文件传输、编写与运行。

一、程序改进

  在前面产生学生成绩分布的时候，由于对于超过100之后的分数都设定为99分，造成成绩几种在99分的比较严重，下面对于产生测试学生成绩的Python做些改动。

1、改动后的Python程序

from headm import *
from numpy import *

outfilename = 'score.txt'

student_number = 199
score_average = 85
score_variance = 15

score = random.normal(score_average,
                      score_variance,
                      student_number)

score = [s if s < 100 else 100-s/5 for s in score]
score = [s if s > 0 else 0 for s in score]
score = [floor(s*10)/10 for s in score]

with open(outfilename, 'w') as f:
    for i in range(student_number):
        student_id = '202109%03d'%(101+i)
        f.write('%s,%3.1f\n'%(student_id, score[i]))

printf(score)
plt.hist(score)
plt.xlabel("分数段")
plt.ylabel("人数")
plt.title('成绩分布')
plt.grid(True)
plt.tight_layout()
plt.show()
