C++ STL string迭代器的使用

代码如下:

#define  _SCL_SECURE_NO_WARNINGS

#include 
#include 	//要与c语言里面的#include 区分
using namespace std;

int main(){

	string str("abcdefg");
	string::iterator ite;

	ite = str.begin();
	for (size_t i = 0; i < str.size(); i++){
		cout << *ite;
		ite++;
	}
	ite = str.begin();
	cout << endl;
	for (size_t i = 0; i < str.size(); i++){
		cout << ite[i];
	}
	cout << endl;
	ite = str.begin();
	for (; ite != str.end(); ite++){
		cout << *ite;
	}

	cout << endl;

	str.append(10, 'a');
	//cout << ite[16] << endl; 迭代器失效

	system("pause");
	return 0;
}
