1. 编写一个C++程序,它显示您的姓名和地址。
#include<iostream>
using namespace std;
int main(void)
{
cout << "My name is YoRHa,l live in Shanghai" << endl;
return 0;
}
输出结果:![]()
2.编写一个CH程序,它要求用户输入一个以long为单位的距离,然后将它转换为码(一long等于220码)。
#include<iostream>
using namespace std;
double long_to_yard(double long1);
int main(void)
{
double long1;
cout << "Gvie long: ";
cin >> long1;
double yard1;
yard1 = long_to_yard(long1);
cout << long1 << " long= "
<< yard1 << " yard." << endl;
return 0;
}
double long_to_yard(double long1)
{
return 200 * long1;
}
输出结果:
3.编写一个C++程序,它使用3个用户定义的函数(包括main( )),并生成下面的输出:
Three blind mice
Three blind mice
See how they run
See how they run
include<iostream>
using namespace std;
void print_mice(void);
void print_run(void);
int main(void)
{
print_mice();
print_mice();
print_run();
print_run();
return 0;
}
void print_mice(void)
{
cout << "Three blind mice." << endl;
}
void print_run(void)
{
cout << "See how the run." << endl;
}
输出结果:
4.编写一个程序,让用户输入其年龄,然后显示该年龄包含多少个月,如下所示:Enter your age:29
#include<iostream>
using namespace std;
int age_to_month(int age);
int main(void)
{
int age;
cout << "Enter your age: ";
cin >> age;
int months;
months = age_to_month(age);
cout << "This age include " << months << " month" << endl;
return 0;
}
int age_to_month(int age)
{
return age*12;
}
输出结果:
5.编写一个程序,其中的main()调用一个用户定义的函数(以摄氏温度值为参数,并返回相应的华氏温度值)。该程序按下面的格式要求用户输入摄氏温度值,并显示结果:
Please enter a celsius value: 20
20 degrees celsius is 68 degrees Fahrenheit.
下面是转换公式:华氏温度=1.8×摄氏温度+32.0
#include<iostream>
using namespace std;
double convert(double c);
int main(void)
{
double c_degree,f_degree;
cout << "Please enter a Celsius value: ";
cin >> c_degree;
f_degree = convert(c_degree);
cout << c_degree << " degrees Celsius is "
<< f_degree << " degrees Fahrenheit." << endl;
return 0;
}
double convert(double c)
{
return 1.8 * c + 32;
}
输出结果:
7.编写一个程序,要求用户输入小时数和分钟数。在main()函数中,将这两个值传递给一个void函数,后者以下面这样的格式显示这两个值:
Enter the number of hours: 9
Enter the number of minutes: 28
Time:9:28
#include<iostream>
using namespace std;
void show(int h,int m);
int main(void)
{
int hour,minute;
cout << "Enter the number of hours: ";
cin >> hour;
cout << "Enter the number of minutes: ";
cin >> minute;
show(hour,minute);
return 0;
}
void show(int h,int m)
{
cout << "Time: " << h <<":" << m << endl;
}
输出结果:
1370
