功能应该有一个原型 [英] function should have a prototype

问题描述

大家好，


我是C ++的新手...我试着编译以下程序...


#include< ; iostream.h>

#include< conio.h>

#include< string>

#include< stdio.h>


int main（）{

String mystr;

cout<< 你的名字是什么？;

getline（cin，mystr）;

cout<< 我的名字是： << mystr;

cout<< 你最喜欢的球队是什么？;

getline（cin，mystr）;

cout<< 我最喜欢的球队是 << mystr;

getch（）;

返回0;

}


但我得到了错误''函数getline应该有一个原型''...我除了这个之外还得到其他错误...但我想如果我可以添加相关的#include ......我可以修复这个错误..任何人都可以告诉我它是什么''getline''函数... thnk in advnce ...

解决方案

它''您缺少的命名空间。您可以使用std :: getline或在包含以下内容后添加此行：

< blockquote>

我想要添加到上面的回复。在包含标准c ++库时，您应该避免使用.h。所以最好使用

展开 | 选择 | Wrap | 行号

即使他没有使用名称空间，他也很容易做到：

Hi all,

I am new to C++...I tried to compile the following program...

#include<iostream.h>
#include<conio.h>
#include<string>
#include<stdio.h>

int main() {
String mystr;
cout << "What is your name?";
getline(cin,mystr);
cout << "my name is:" << mystr;
cout << "What is your favourite team?";
getline(cin, mystr);
cout << "My favourite team is " << mystr;
getch();
return 0;
}

but i am getting the error ''function getline should have a prototype''...I am getting other errors as well apart from this ...but i think if i can add the relevant "#include..." i can fix this error..can anyone please tell me what is it for ''getline'' function...thnk in advnce...

It''s namespace that you are missing.You can use std::getline or add this line after includes:

I would like to add to the above reply. You should refrain from using the .h when including standard c++ libraries. So preferably use

Expand|Select|Wrap|Line Numbers

Well even if he didn''t use the namespace he could easily do:
