C语言单词排序问题

[zzzzz111112222333333]

问题是这样的

我写的代码是这样的

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

int main()
{
    char words[101][52]={0};
    int i,cnt=0,j,k;
    char word[5100];
    char buff[52];
    i=0;j=0,k=0;
    gets(word);
    char*token=strtok(word," ");//分割
    while(token!=NULL)
    {
        strcpy(words[i],token);
        token=strtok(NULL," ");
        cnt++;i++;
    }

    for(i=0;i<cnt-1;i++)//选择排序
    {
        j=i;
        for(k=i+1;k<cnt;k++)
        {
            if(strcmp(words[j],words[k])==1)
            {
                j=k;
            }
        }
        strcpy(buff,words[i]);
        strcpy(words[i],words[j]);
        strcpy(words[j],buff);
    }
    for(i=0;i<cnt;i++)//输出
    {
        if(strcmp(words[i],words[i+1])==0)
        {
            continue;
        }
        if(i!=cnt-1)
            puts(words[i]);
        else
            printf("%s",words[i]);
    }

    return 0;
}

问题是，提交只有3分，不知哪些数据出了问题。多个空格，重复单词，一开始就有空格这些都没问题，已经解决

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

int main()
{
    char words[101][52]={0};
    int i,cnt=0,j,k;
    char word[5100];
    char buff[52];
    i=0;j=0,k=0;
    gets(word);
    char*token=strtok(word," ");//分割
    while(token!=NULL)
    {
        strcpy(words[i],token);
        token=strtok(NULL," ");
        cnt++;
        i++;
    }

    /*
    printf("cnt = %d\n", cnt);
    for (i = 0; i < cnt; i++)
        printf("words[%d] = %s\n", i, words[i]);
    */

    for(i = 0; i < cnt-1; i++)
    {
        j = i;
        for(k = i + 1; k < cnt; k++)
            if(strcmp(words[j], words[k]) > 0)
                j = k;
        if (j != i) {    /*交换条件*/
            strcpy(buff, words[i]);
            strcpy(words[i], words[j]);
            strcpy(words[j], buff);
        }
    }
    /*
    for (i = 0; i < cnt; i++)
        printf("words[%d] = %s\n", i, words[i]);
    */
    for(i = 0; i < cnt; i++)//输出
    {
        if(strcmp(words[i], words[i+1])==0)
        {
            continue;
        }
        if(i!=cnt-1)
            puts(words[i]);
        else
            printf("%s",words[i]);
    }

    return 0;
}

参考一下吧 主要是选择排序的问题，选择排序算法写的有点问题，详见上面的代码；

提交了第3次才成功，开始忘记删除了重复了，第二次输出没有分行，改正通过，用C++的算法也没事

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <algorithm>
#include <string>
#include <vector>
using namespace std;

int main()
{
    vector<string> words;
    int cnt = 0;

    char word[5100];

    gets(word);

    char* pch = strtok(word, " \t"); //分割
    while (pch != NULL) {
        words.push_back(string(pch));
        pch = strtok(NULL, " \t\n");
        cnt++;
    }

    // 排序和删除重复
    std::sort(words.begin(), words.end());
    auto it = unique(words.begin(), words.end());
    words.erase(it, words.end());

    for (auto it = words.begin(); it != words.end(); it++) { //输出
        printf("%s\n", it->c_str());
    }
    return 0;
}
