计算文本中各个单词的字数并输出(代码我重写了一遍，但发现执行后会输出乱码，请问怎么回事？代码在六楼)

执行后发现每次只能输出两个词，不知为啥？？帮忙看看。谢谢

程序代码：

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

#define TEXT_LEN 10000        //maximum length of the text
#define BUF_LEN 100                //the maximum length of each time of input
#define WORDS_MAX 500     //there are at most 500 words
#define WORDS_LEN 12     //length of each word should smaller than 12

int main()
{
    char delimiters[]=" \n,.?;!";
    char text[TEXT_LEN];                    //store the whole text
    char buf[BUF_LEN];                        //store one input line
    char words[WORDS_MAX][WORDS_LEN];   //store all the words
    int nword[WORDS_MAX]={0};                //store the number of words occurrences
    int word_count=0;                                            //the number of words
   

    printf("please enter strings.Enter an empty line to end input\n");
                //start to input........
    while(1)
    {
        fgets(buf,BUF_LEN,stdin);
        if(buf[0]=='\n')
            break;
        if(!strcat(text,buf))
        {
            printf("error!!!\n");break;
        }
    }
                   

    char *pword=strtok(text,delimiters);
    if(!pword)
    {
        printf("there is no word\n");return 1;
    }
    strcpy(words[word_count],pword);
    ++nword[word_count++];
   

    bool new_word=true;    //找到的单词已存在words中就是false否则就是true

    while(true)
    {
        pword=strtok(NULL,delimiters);
        if(!pword)
            break;
        for(int i=0;i<word_count;i++)   //old word
            if(strcmp(words[i],pword)==0)
            {
                nword[i]++;
                new_word=false;
            }
        if(new_word)                                                //new word
        {
            strcpy(words[word_count],pword);
            ++nword[word_count++];
        }
        else
            new_word=true;
        if(word_count>WORDS_MAX)
        {
            printf("there are too many words");
            return 1;
        }
       

        //list all the words
        for(int i=0;i<word_count;i++)
        {
            printf("%-13s %3d  ",words[i],nword[i]);
            if((i+1)%2==0)
                printf("\n");
        }
        printf("\n");
        return 1;
    }

2楼我给你改过了， char text[TEXT_LEN] = {0}; //store the whole text
要仔细啊！

楼主用的是什么软件？不能把主动关键字特殊标示吗？从134开始出现错误都是关于new关键字的，我把你变量名改了，已能顺利编译。

像我用的Dev C++，直接看颜色就知道那是个保留字不能用作变量命名

程序代码：

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

#define TEXT_MAX 1000
#define BUF_SIZE 50
#define WORDS_MAX 500
#define WORDS_LEN 13

int main()
{
    char delimiters[]=" ,.?!;\n";
    char text[TEXT_MAX];
    char buf[BUF_SIZE];
    char words[WORDS_MAX][WORDS_LEN];
    int nwords[WORDS_MAX]={0};
    int count=0;


    printf("please enter strings(end input with an empty line)\n");
    while(1)
    {
        fgets(buf,BUF_SIZE,stdin);
        if(buf[0]=='\n')
            break;
        if(!strcat(text,buf))
        {
            printf("error\n");
            break;
        }
    }


    bool newFlag=true;//<-new 是一个关键字，具体作用请百度
    char *p=strtok(text,delimiters);
    if(!p)
    {
        printf("there is nothing\n");
        return 0;
    }
    strcpy(words[count],p);
