这在C ++中看起来如何 [英] How this looks in C++

问题描述

我是C ++的新手，之前我使用的是Pascal。所以，我在Pascal中做了这个练习，我对它在C ++中的外观感兴趣。我只知道C ++中的基本内容：数组，循环内容等。这是Pascal代码：

I'm new to C++, previously I used Pascal. So, I did this exercise in Pascal and I'm interested in the way how this looks in C++. I only know the basic things in C++: arrays, loop stuff etc. Here's the Pascal code:

program asd;
    uses crt;
    var
    letters: set of 'A'..'Z';
    kar: char;

    Begin
    clrscr;

    letters:=[];
    while kar <> #27 do begin
    if keypressed then begin
    kar:=readkey;
    if kar=#0 then begin
    kar:=readkey;
    kar:=#0;
    end;
    kar:=upcase(kar);
    writeln(kar);
    if kar in ['A'..'Z'] then
    letters:=letters+[kar];
    end;
    end;

    write('read letters from keyboard: ');
    for kar:='A' to 'Z' do begin
    if kar in betuk then
    write(kar);
    end;
    writeln;


    write('not read letters from keyboard: ');
    for kar:='A' to 'Z' do begin
    if not(kar in letters) then write(kar);
    end;

    readln;
    end.

它从键盘读取字符，直到我按ESC，然后写出字符并且人物留在了ABC。 （抱歉我的英文不好，不是我的母语）。

It reads characters from keyboard until I press ESC, and write out the characters and the characters remained in the ABC. (Sorry for my bad English, it isn't my native language).

推荐答案

所以用C ++编写代码并试用。

我们很乐意批评你做了什么，但我们不会为你转换它！

So code it up in C++ and try it out.
We'll happily criticise what you did, but we aren't going to convert it for you!
