昨天有个网友问相似的问题，不过只有一个句子，稍微改了下弄成能处理多个句子的。 #include <stdio.h>const int MAX_NUM_OF_WORDS=30;const int MAX_LEN_OF_WORDS=30;int main(){        char sample_sentence[]="You can, count,  how    many words these sample sentences has  . This is the second sentence  .  Third one.";        char words[MAX_NUM_OF_WORDS][MAX_LEN_OF_WORDS];    int CountWords(char* str,char words[][MAX_LEN_OF_WORDS]);    int num_of_sentences=0;    int num_of_words;     //    =CountWords(sample_sentence,words);    char *p_first_char=sample_sentence;    int i,j,iSentence=0;        puts("段落如下：");    puts(sample_sentence);    putchar('\n');    for(i=0;i<sizeof(sample_sentence)-1;i++)    {        if(sample_sentence[i]=='.') num_of_sentences++;    }    printf("段落中共有%d个句子，句子如下：\n\n",num_of_sentences);    for(i=0;i<sizeof(sample_sentence)-1;i++)    {        if(sample_sentence[i]=='.')        {            num_of_words=CountWords(p_first_char,words);            iSentence++;            printf("第%d个句子有%d个单词，单词如下：\n",iSentence,num_of_words);            for(j=0;j<num_of_words;j++)                printf("\"%s\" ",words[j]);            printf("\n\n");            if(iSentence!=num_of_sentences)            {                for(j=1;sample_sentence[i+j]==' ';j++);                p_first_char=&sample_sentence[i+j];            }            else                break;        }    }        getchar();    return 0;}int CountWords(char *str,char words[][MAX_LEN_OF_WORDS]){    int num_of_words=0;    while(true)    {            int num_of_chars=0;        for(;*str!=' ' && *str!=',' && *str!='.';words[num_of_words][num_of_chars++]=*str++);        words[num_of_words++][num_of_chars]='\0';        if(*str==',') str++;        if(*str==' ') while(*++str==' ');        if(*str=='.') break;    }    return num_of_words;}输出如下：段落如下：You can, count,  how    many words these sample sentences has  . This is the second sentence  .  Third one.段落中共有3个句子，句子如下：第1个句子有10个单词，单词如下："You" "can" "count" "how" "many" "words" "these" "sample" "sentences" "has"第2个句子有5个单词，单词如下："This" "is" "the" "second" "sentence"第3个句子有2个单词，单词如下："Third" "one"
