为什么我收到错误"cin没有命名类型"

Question

在尝试编写此代码时,出现错误"cin doesnt name a type".我不知道究竟是什么问题,我试着写"using namespace std;" 但它给出了同样的错误.

这是代码

#include<iostream>

namespace myStuff {

    int value = 0;

}

using namespace myStuff;

int main {

    std::cout << "enter integer " << ;
    std::cin >> value;
    std::cout << "\nyouhaveenterd a value" << value ;

    return 0;

}

这是编译错误:

: extended initializer lists only available with `-std=c++0x` or `-std=gnu++0x` [enabled by default]|
: expected primary-expression before ‘;’ token|
 expected `}` before `;` token|
 `cin` does not name a type|
: `cout` does not name a type|
: expected unqualified-id before `return`|
: expected declaration before `}` token|

Answer 1

int main{

应该

int main(){

和

std::cout << "enter integer " << ;

应该

std::cout << "enter integer ";
