实验报告课程名称：VC++面向对象与可视化程序设计实验项目：平均学分绩点计算器专业班级：电子信息工程1003班姓名：邓运思学号：100402317实验室号：信息205 实验组号：17实验时间：2012/12/10批阅时间：指导教师：伞宏力成绩：沈阳工业大学实验报告（适用计算机程序设计类）专业班级：电子信息1003班学号：100402317 姓名：邓运思实验名称：平均学分绩点计算器1.实验目的：掌握使用VC++6.0为编程开发环境，进行简单的可视化编程设计一个学分绩点计算器，并能按要求进行计算2.实验内容：建立类型为基本对话框的工程熟练掌握简单控件的用法学习掌握计算的算法3. 实验方案（程序设计说明）算法：平均学分绩点=各科成绩*各科对应的学分/学分之和界面设计：分两个学年（包括成绩输入，学分输入，是否从修的选择），有时间显示，计算结果的输出，对结果的相关提示，插入图片，连接网站，背景颜色设置，字体设置设计流程图：建立工程：界面：控件：用到的有静态，组框，组合框，编辑，复选框，按钮，图像等控件退出对话框：4. 实验步骤或程序（经调试后正确的源程序）见附件A5.程序运行结果6．出现的问题及解决办法1.组合框无法清零解决办法：找到.SetCurSel()函数，括号里的值为-12.保留计算结果后2位有效数字解决办法：a1=pjxfjd*1000.0;a2=pjxfjd*100.0;a3=a1%10;if(a3>=5){a4=a2+1;}else{a4=a2;}a5=a4/100.0;这种方法还保证了进位3.计算有负位解决办法：有时输入的不合理造成不对的输出结果，所以给输出加限制条件4.加入图片解决办法：须转换为8位256色数的BMP格式的图片7.心的体会附件A
