一、Dev-C++配置EasyX库
EasyX 是针对 C/C++ 的图形库,可以帮助使用C/C++语言的程序员快速上手图形和游戏编程。比如,可以用 EasyX 很快的用几何图形画一个房子,或者一辆移动的小车,可以编写俄罗斯方块、贪吃蛇、黑白棋等小游戏,可以练习图形学的各种算法,等等。
安装
下载地址:https://www.easyx.cn/downloads/
下载后解压缩
将easyx.h 和 graphics.h 拷贝到Dev-C++安装路径\MinGW64\x86_64-w64-mingw32\include
将lib32中的libeasyx.a拷贝到Dev-C++安装路径\MinGW64\x86_64-w64-mingw32\lib32
将lib64中的libeasyx.a拷贝到Dev-C++安装路径\MinGW64\x86_64-w64-mingw32\lib
配置编译环境
创建新项目:菜单 -> 新建 -> 项目,选择 Console Application,项目名称 如项目1(根据自己的情况填写),语言选择 C++,点击确定,参见下图:
测试``
#include <graphics.h>
#include <conio.h>
int main()
{
initgraph(640, 480);
circle(400, 240, 100);
getch();
closegraph();
return 0;
}
设置链接库:菜单 项目-> 项目属性…,选择选项卡参数,然后在 链接 区域点按钮 逐个添加:libeasyx.a、libgdi32.a、libole32.a,或者也可以直接输入 -leasyx -lgdi32 -lole32,完成。 编译后结果
二、考勤管理系统的搭建
1.功能描述
该考勤系统使用图形化编程实现了包括浏览学生考勤信息,对学生考勤信息排序,查询学生考勤信息,删除学生考勤信息,修改学生考勤信息,求平均,旷课次数最多与最少同学等功能。
2.代码
代码如下(示例):
#include <bits/stdc++.h>
#include<graphics.h>
using namespace std;
#define manx 800
#define NAME 20
#define SEX 10
#define KDAYS 20
#define ADDR 30
#define NUMBER 12
#define DAK 10
#define CLASS 30
#define STUDENTMAX 1000
