Problem Description If you ever tried to read a html document on a Macintosh, you know how hard it is if no Netscape is installed.  Now, who can forget to install a HTML browser? This is very easy because most of the times you don't need one on a MAC because there is a Acrobate Reader which is native to MAC. But if you ever need one, what do you do?  Your task is to write a small html-browser. It should only display the content of the input-file and knows only the html commands (tags)
which is a linebreak and

which is a horizontal ruler. Then you should treat all tabulators, spaces and newlines as one space and display the resulting text with no more than 80 characters on a line.   Input The input consists of a text you should display. This text consists of words and HTML tags separated by one or more spaces, tabulators or newlines.  A word is a sequence of letters, numbers and punctuation. For example, "abc,123"is one word, but "abc, 123"are two words, namely "abc,"and "123". A word is always shorter than 81 characters and does not contain any '<' or '>'. All HTML tags are either
or

.   Output You should display the the resulting text using this rules:    . If you read a word in the input and the resulting line does not get longer than 80 chars, print it, else print it on a new line.    . If you read a
in the input, start a new line.    . If you read a

in the input, start a new line unless you already are at the beginning of a line, display 80 characters of '-' and start a new line (again).  The last line is ended by a newline character. Sample Input Hallo, dies ist eine  ziemlich lange Zeile, die in Html aber nicht umgebrochen wird.

HTMLのテキストを入力し、入力したテキストに基づいてHTMLの言語形式で出力します.
出てきますが、行ごとに80文字を超えてはいけません.超えたものは改行して出力します.
注意:
に遭遇すると改行され、

に遭遇すると次の行に80'-'と入力されます.
考え方:最初にやったときに読み込みながら出力し、最初はPEを2回、ACを変更しました.あとでそう思う
入出力は審美的ではない...大きな文字列に格納してから出力するように変更しました.
これでずっときれいになりました.(ーー゛)...
1回目は入力しながら出力:

#include<iostream>
#include<algorithm>
#include<cstdio>
#include<cstring>
using namespace std;

char s[110];

int main()
{
    int Count = 0;
    while(cin >> s)
    {
        if(strcmp(s,"<br>") == 0)
        {
            cout << endl;
            Count = 0;
            continue;
        }
        if(strcmp(s,"<hr>") == 0)
        {
            if(Count > 0)
            {
                Count = 0;
                cout << endl;
            }

            for(int i = 0; i < 80; ++i)
                cout << '-';
            cout << endl;
            continue;
        }
        int len = strlen(s);
        Count += len;
        if(Count + 1 > 80)
        {
             Count = len;
             cout << endl << s;
        }
        else
        {
            if(Count > len)
                cout << ' ';
            cout << s;
            Count++;
        }
    }
    cout << endl;
    return 0;
}

2パス目はストレージを入力してから出力します.

#include<iostream>
#include<algorithm>
#include<cstdio>
#include<cstring>
using namespace std;

char s[110];
char a[10010];
int main()
{
    int Count = 0;
    int id = 0;
    while(cin >> s)
    {
        if(strcmp(s,"<br>") == 0)
        {
            a[id++] = '
';
            Count = 0;
            continue;
        }
        if(strcmp(s,"<hr>") == 0)
        {
            if(Count > 0)
            {
                Count = 0;
                a[id++] = '
';
            }
            for(int i = 0; i < 80; ++i)
                a[id++] = '-';
            a[id++] = '
';
            continue;
        }
        int len = strlen(s);
        Count += len;
        if(Count + 1 > 80)
        {
             Count = len;
             a[id++] = '
';
            for(int i = 0; i < len; i++)
                a[id++] = s[i];
        }
        else
        {
            if(Count > len)
                a[id++] = ' ';
            for(int i = 0; i < len; ++i)
                a[id++] = s[i];
            Count++;
        }
    }
    a[id] = 0;
        cout << a << endl;
    return 0;
}
