10个比较经典的C++程序。初学者就先多学习学习别人吧。

#include <iostream>
using namespace std ;
int main()
{	cout << "The size of an int is:\t\t" << sizeof(int) << " bytes.\n";
	cout << "The size of a short int is:\t" << sizeof(short) << " bytes.\n";
	cout << "The size of a long int is:\t" << sizeof(long) << " bytes.\n";
	cout << "The size of a char is:\t\t" << sizeof(char) << " bytes.\n";
	cout << "The size of a wchar_t is:\t" << sizeof(wchar_t) << " bytes.\n";
	cout << "The size of a float is:\t\t" << sizeof(float) << " bytes.\n";
	cout << "The size of a double is:\t" << sizeof(double) << " bytes.\n";
	return 0;
}
