C++课程设计题目,包括1、输出10至99之间每位数的乘积大于每位数的和的数,例如对于数字12,有1*22+7,故输出该数。
2、求任意n个数中的最大数和最小数:先输入一个正整数n(个数),而后再输入任意n个实数,找出这n个数中的最大数及最小数并显示出来。
3、对两个有序数组进行合并:设有如下数组A、B,并假设两个数组的元素都已经有序(从大到小降序排列)。
编程序,合并A、B数组形成一个新的数组C,并使C的元素仍有序(从大到小降序排列)。
intA[10]={123,86,80,49,33,15,7,0,-1,-3};
intB[10]={100,64,51,50,27,19,15,12,5,2};
4、有一个分数序列:1/2,1/3,1/4,1/5,1/6,1/7,……,编写函数求序列前n项之和,要求在主程序中提示用户输入整数n,并判断所输入数是否合法(大于1为合法),如果合法则调用求和函数并输出结果。
5、计算两个日期之间的间隔天数:从键盘输入两个日期(如以year1,month1,day1以及year2,month2,day2的方式来输入它们),而后计算出这两个日期的间隔天数并在屏幕上显示出结果。
要求编制具有如下原型的函数difs2Date:longGetDayDifference(inty1,intm1,intd1,inty2,intm2,intd2);
并在主函数中调用向屏幕上输出计算结果。
7、声明并定义一个日期类CDate,其中数据成员m_iYear,m_iMonth,m_iDay,分别表示年、月、日,成员函数SetDate()用来设置年、月、日,成员函数IsLeapYear()用来判断当前的年份是否为闰年,构造函数带有默认形参值,可接收外部参数对m_iYear,m_iMonth,m_iDay进行初始化,另要求编写测试程序,定义一个CDate类对象,将其日期设置为2005年1月1日,调用成员函数IsLeapYear()判断该年份是否为闰年,并输出判断结果.说明:闰年的年份可以被4整除而不能被100整除,或者能被400整除.8、编写一个程序计算两个给定长方形的面积,其中在设计类成员函数GetTotalArea()(用于计算两个长方形的总面积)时使用对象作为参数。
9、设计一个时间类Time,包括3个数据成员,时(h)、分(m)、秒(s),另外包括存取各数据成员和设置时间的成员函数,按上、下午各12小时或按24小时输出时间的成员函数,以及默认构造函数,默认时间值为0时0分0秒。
10、编写一个程序,输入3个学生的英语和计算机成绩,并按总分从高到低排序(要求设计一个学生类Student)。
11.求解一元二次方程。
一元二次方程的定义为:ax2+bx+c=0(1)如果b2-4ac>0,方程有两个不同的实根,分别是:(2)如果b2-4ac<0,方程没有实根,但有虚根;
(3)如果b2-4ac=0,方程有一个实根。
请你编写一个程序,使其能求出多个二次方程的根。
该程序要询问用户是否想继续解下一个方程。
用户输入1来继续,输入其它数字,则终止程序。
程序要求用户输入a,b和c,然后根据前面的条件计算,并输出答案。
要求:使用类实现,(1)a,b,c为该类的私有成员变量;
(2)求根的实现为该类的成员函数,形式为://函数返回值:实根的个数;
//参数:x-用以返回实根值的数组;
intCalResult(doublex[]);(3)该类还包含有参构造函数、析构函数。

在日常工作中,钉钉打卡成了我生活中不可或缺的一部分。然而,有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚,我总是得牢记打开钉钉应用,点击"工作台",再找到"考勤打卡"进行签到。有时候因为工作忙碌,会忘记打卡,导致考勤异常,影响当月的工作评价。而且,由于我使用的是苹果手机,有时候系统更新后,钉钉的某些功能会出现异常,使得打卡变得更加麻烦。 另外,我的家人使用的是安卓手机,他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说,每次打卡都是一次挑战。他们总是担心自己会操作失误,导致打卡失败。 为了解决这些烦恼,我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习,我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
