PRINT_ELEMENTS的实现

void PRINT_ELEMENTS(const T& coll, const char* optcstr = " ") {
	typename T::const_iterator pos;

	cout << optcstr;

	for (pos = coll.begin(); pos != coll.end(); ++pos) {
		cout << *pos <<" ";
	}

	cout << endl;
}

一个案例实现：

#include<iostream>
#include<cstdlib>
#include<string>
using namespace std;
template <class T>
void PRINT_ELEMENTS(const T& coll, const char* optcstr = " ") {
	typename T::const_iterator pos;

	cout << optcstr;

	for (pos = coll.begin(); pos != coll.end(); ++pos) {
		cout << *pos <<" ";
	}

	cout << endl;
}
int main()
{
	char name1[10];
	char name2[10];
	cin.get(name1,9,'.');
	cin >> name2;

	PRINT_ELEMENTS(static_cast<string>(name1));

	PRINT_ELEMENTS(static_cast<string>(name2));
	cin.get();
	cin.getline(name1, 9, '.');
	cin >> name2;

	PRINT_ELEMENTS(static_cast<string>(name1));

	PRINT_ELEMENTS(static_cast<string>(name2));

	system("pause");
}

输入：123.456 123.456

输出结果：
