什么是C ++中的EOF键 [英] what is EOF key in C++

问题描述

我正在使用Windows 7旗舰版。我是C ++的新手。以下是我对switch语句的练习。

I am using Windows 7 Ultimate. I am new to C++. Following is my exercise for switch statement.

void GradeBook::inputGrades()
{
    int grade;

    cout << "Enter Grade: " << endl;

    while((grade=cin.get()) != EOF)
    {
       switch(grade)
        {
            case 'A':
            case 'a':
                aCount++;
                break;

            case 'B':
            case 'b':
                bCount++;
                break;

            case 'C':
            case'c':
                cCount++;
                break;

            case 'd':
            case 'D':
                dCount++;
                break;

            case 'F':
            case 'f':
                fCount++;
                break;

           case '\n':
           case ' ':
           case '\t':
               break;

            default:
                cout << "Incorrect data. Re Enter" << endl;
                break;
        }

    }
}

我跑这个内部netbeans，我按下所有组合ctrl + c，ctrl + z，ctrl + d但它没有结束!!这是为什么？我做错了什么吗？请帮助!!

I run this inside netbeans, and I pressed all the combinations ctrl+c , ctrl+z, ctrl+d but it is not ending!! Why is that? Have I done something wrong? Please help!!

推荐答案

EOF字符是Ctrl + Z，后跟Windows平台上的换行符。

An EOF character is Ctrl+Z followed by a newline character on Windows platforms.

据推测，Netbeans中的控制台也是如此。

Presumably that will be the same for the console within Netbeans.
