1.使用一个整数输入自己的身高(单位为cm),并将此身高转化为米和厘米共同表示的形式,使用下划线字符来指示输入的位置,使用一个const符号常量来表示转换因子。

#include<iostream>
using namespace std;
const int transform = ;
int main()
{
cout << "请输入自己的身高,单位为厘米:___\b\b\b" ;//使用下划线字符来指示输入的位置
int height;
cin >> height;
cin.get();
cout << "你的身高是: " << height << "公分" << endl;
int meter;
meter = height / transform;
int cm;
cm = height % transform;
cout << height << "公分是" << meter << "米加" << cm << "厘米" << endl;
cin.get();
return ;
}

运行结果:  

  请输入自己的身高,单位为厘米:190
  你的身高是: 190公分
  190公分是1米加90厘米

2.要求以几英尺几英寸的方式输入身高,并以磅为单位输入其体重,计算IBM指数。

#include<iostream>
using namespace std;
const double Inch2Meter = 0.254;
const double Kilo2Pound = 2.2;
const int Foot2Inch = ; int main()
{
double height_foot = 0.0;
double height_inch = 0.0;
double height_meter = 0.0;
double weight_pound = 0.0;
double weight_kilo = 0.0;
double BMI = 0.0; cout << "Enter your height in foot and inch" << endl;
cout << "First enter the foot: ";
cin >> height_foot;
cin.get();
cout << "Second enter the inch: ";
cin >> height_inch;
cin.get();
cout << "Enter you weight in pound: ";
cin >> weight_pound;
cin.get();
height_meter = (height_foot * Foot2Inch + height_inch) * Inch2Meter;
weight_kilo = weight_pound / Kilo2Pound; BMI = weight_kilo / (height_meter * height_meter); cout << "Your BIM is " << BMI << endl;
cin.get();
return ;
}

运行结果:  

  Enter your height in foot and inch
  First enter the foot: 12
  Second enter the inch: 45
  Enter you weight in pound: 6
  Your BIM is 0.00118342

3.要求用户以度,分,秒的方式输入一个纬度,然后最终以度为单位显示该纬度。

#include<iostream>
using namespace std;
int main()
{
double degress = 0.0;
double minutes = 0.0;
double seconds = 0.0; cout << "Enter a latitude in degrees,minutes,and seconds:" << endl;
cout << "First enter the the degress: ";
cin >> degress;
cin.get();
cout << "Second enter the minutes: ";
cin >> minutes;
cin.get();
cout << "Finally ,enter the seconds : ";
cin >> seconds;
cin.get(); double last = seconds / / + minutes / + degress; cout << degress << " degress, " << minutes << " minutes, " << seconds << " seconds = " << last << " degrees" << endl;
cin.get();
return ;
}

运行结果:

  Enter a latitude in degrees,minutes,and seconds:
  First enter the the degress: 37
  Second enter the minutes: 51
  Finally ,enter the seconds : 19
  37 degress, 51 minutes, 19 seconds = 37.8553 degrees、

4. 要求用户以整数方式输入秒数,然后以天、小时、分钟和秒的方式显示这段时间。

#include<iostream>
using namespace std;
int main()
{
long total = 0.0;
cout << "请输入秒数,我给您以天、小时、分钟和秒的方式显示这段时间: " ;
cin >> total;
cin.get(); int days;
int hours = ;
int minutes = ;
int seconds = ; days = total / ( * * );
hours = ((total % ( * * )) / ( * ));
minutes = ((total % ( * )) / );
seconds = (total % ); cout << "该段时间为:" << days << " 天 " << hours << " 小时 " << minutes << " 分钟 " << seconds << " 秒 " << endl;
cin.get();
return ;
}

运行结果:  

  请输入秒数,我给您以天、小时、分钟和秒的方式显示这段时间: 4556652
  该段时间为:52 天 17 小时 44 分钟 12 秒
