题目其实不难，但是要注意题目的要求，当前字数（>0）+当前单词长度+1若超过80则需要回车后，输出当前word，并且重新计数。这道题目的数据感觉比较水，不过测试的时候，最后使用fprintf输出在文件中，便于观察。

#include <stdio.h>
#include <string.h>

#define MAXNUM 85

char line[MAXNUM];
char word[MAXNUM];

int main() {
    int i;
    int num=0, len;
    //FILE *fout = fopen("data", "w");

    while (scanf("%s", word) != EOF) {
        if (strcmp(word, "<br>") == 0) {
            printf("\n");
            //fprintf(fout, "\n");
            num = 0;
            continue;
        }
        if (strcmp(word, "<hr>") == 0) {
            if (num)
                printf("\n");
                //fprintf(fout, "\n");
            for (i=0; i<80; ++i)
                printf("-");
                //fprintf(fout, "-");
            printf("\n");
            //fprintf(fout, "\n");
            num = 0;
            continue;
        }
        len = strlen(word);
        if (num) {
            if (num+len+1 > 80) {
                printf("\n%s", word);
                //fprintf(fout, "\n%s", word);
                num = len;
            } else {
                printf(" %s", word);
                //fprintf(fout, " %s", word);
                num += len+1;
            }
        } else {
            printf("%s", word);
            //fprintf(fout, "%s", word);
            num += len;
        }
    }
    printf("\n");
    //fclose(fout);

    return 0;
}
