梦回C语言，一开始头文件还是会习惯打成stdio，看完第二章感觉和C还是差不多的，学这本主要是想搞懂C++语法和类对象的概念，不过前几张好像和C都差不多。–3.25

CH02 Code Answer 1:

#include <iostream>

//using namespace std;

int main(void)
{
//	using std::cout;
	std::cout << "P.Z TIME!";
	
	return 0;
}

CH02 Code Answer 2:

#include <iostream>

using namespace std;

int main(void)
{
	long n;
	cin >> n;
	cout << "Translate: " << n * 220 << "!";
	
	return 0;
}

CH02 Code Answer 3:

#include <iostream>

using namespace std;

void Print1(void);
void Print2(void);

int main(void)
{
	Print1();
	Print1();
	Print2();
	cout << endl;
	Print2();

	return 0;
}

void Print1(void)
{
	cout << "Three blind mice" << endl;
}

void Print2(void)
{
	cout << "See how they run";
}

CH02 Code Answer 4:

#include <iostream>

using namespace std;

int main(void)
{
	int age;
	cout << "Enter your age:";
	cin >> age;	
	cout << "Your have been to live " << age * 12 << " months in the world!"; 
	
	return 0;	
} 

CH02 Code Answer 5:

#include <iostream>

using namespace std;

double CelsiusToFahrenheit(double celsius);

int main(void)
{
	double celsius;
	cout << "Please enter a Celsius value: ";
	cin >> celsius;
	cout << celsius << " degrees Celsius is " << CelsiusToFahrenheit(celsius) << " degrees Fahrenheit!";
	
	return 0;
}

double CelsiusToFahrenheit(double celsius)
{
	return celsius * 1.8 + 32;
}

CH02 Code Answer 6:

#include <iostream>

using namespace std;

double LightToAstronomical(double light);

int main(void)
{
	double light;
	cout << "Enter the number of light years: ";
	cin >> light;
	cout << light << " light years = " << LightToAstronomical(light) << " astronomical units.\n";
	cout << "You like this number. Right?";
//  See you in galaxy.
	return 0;	
} 

double LightToAstronomical(double light)
{
	return light * 63240;
}

CH02 Code Answer 7:

#include <iostream>

using namespace std;

void ShowTime(int hours, int minutes);

int main(void)
{
	int hours, minutes;
	
	cout << "Enter the number of hours: ";
	cin >> hours;
	cout << "Enter the number of minutes: ";
	cin >> minutes;
	ShowTime(hours, minutes);
	
	return 0;
}

void ShowTime(int hours, int minutes)
{
	cout << "Time: " << hours << ":" << minutes;
}
