如何在c++中检测“输入密钥”？-howtodetect'EnterKey'inc++?

I want to detect enter pressed to break loop. If user press 2 enters in a row, loop breaks. I'm using vector to store user input. All variable's type is integer.

我想检测输入按下以打破循环。如果用户按2进入一行,则循环中断。我正在使用vector来存储用户输入。所有变量的类型都是整数。

#include 
#include 

using namespace std;

int main()
{   int buffer;
    vector frag;
    do
    {
        cin >>buffer;
        frag.push_back(buffer);
    }while(frag.end()!='\n');


}

How can I escape from error message "no match for 'operator!=' (operand types are 'std::vector::iterator....."?

如何从错误消息“不匹配'运算符!='中逃脱(操作数类型是'std :: vector :: iterator .....”?

std::vector vecInt;
char c;

while(std::cin.peek() != '\n'){
    std::cin.get(c);

    if(isdigit(c))
        vecInt.push_back(c - '0');
}

for (int i(0); i
