Ⅱ 大学，C语言程序设计课程设计，至少编写代码300行左右
这种题目很多比如员工管理系统，图书管理系统，电话本之类的而且代码在网上都很好找，因为太多了，最主要的是完整的设计也很多，比如员工管理系统这样的完整的设计和代码直接网络就行了，当然如果你只是想完成作业这些就够了，你要是想自己研究就要你自己参考了，不过既然你在这提问了也就是说你是第一种，所以去网络吧

账户数据文件名已经设定为account.txt，这个文件要和上面这个程序放在同一个文件夹下面，不然就得用绝对路径(比如"d:\\book\\account.txt")，account内容可以用记事本打开自己改动，然后运行程序后就可以在程序中添加或删除
Ⅳ C语言程序设计课程设计！
图书借阅管理，C语言编程的，只要设计部分的，，m
Ⅳ 《C语言程序设计》课程设计实验报告
呵呵~!竟然把作业也搞上来了~!我只能告诉你怎么做.不可以帮你做~!分为三步. 秒针 一个原点 60个秒点分针 一个原点 60个分点时针 一个原点 12个时点三个原点可以是同一个变量,分针\秒针的秒点和分点可以用同一个60个数的数组很简单的.然后用date函数复制..只要做三个循环就可以了..如果厉害的话。 一个循环就搞定了~!
Ⅵ C语言程序设计 课程设计
代码如下，请采纳
int main()
{
double a;
scanf("%lf", &a);
printf("%.2lf", a);
}
Ⅶ c语言程序设计作业 课程设计要求: 1.本课程设计作为《程序设计基础（C语言）》的期末考查，占学期总成绩的7
这个的自己做，作人要厚道
