string

[jenhi]

请问高手：
在c/c++里面想用string类型，怎么用呢？
为什么我#include <string> 后还是不行？

Example
// string_getline_sample.cpp
// compile with: /EHsc
// Illustrates how to use the getline function to read a
// line of text from the keyboard.
//
// Functions:
//
// getline Returns a string from the input stream.
//////////////////////////////////////////////////////////////////////

#pragma warning(disable:4786)
#include <string>
#include <iostream>

using namespace std ;

int main()
{
string s1;
cout << "Enter a sentence (use <space> as the delimiter): ";
getline(cin,s1, ' ');
cout << "You entered: " << s1 << endl;;
}
Input
test this
Sample Output
Enter a sentence (use <space> as the delimiter): test this
You entered: test
Requirements
Header: <string>

头文件加错了,不过是什么我也不知道,嘿嘿

[piaochen_2002]

#include <string.h>

#include<string>// 应用string摸板类要用的头文件

[Seu_why]

#include <string>
using namespace std;

[jenhi]

应用string摸板类要用的头文件

我就是要在程序中这样声明：
string str;

不行啊。能不能说详细点啊？

[piaochen_2002]

#include <string>
#include<isotream>
using namespace std;

[piaochen_2002]

#include <string>
#include<iostream>
using namespace std;

[jenhi]

using namespace std;
在C里这句表示什么？

[jenhi]

为什么还要
#include <iostream>跟
using namespace std;

[bobob]

using namespace std;
使用标准名字空间

[Seu_why]

为什么加using namespace std;
去看 C++ prime
