需求

从文本文件中逐行读取内容，并对读取到的每一行数据字符串进行分割
比如某一行数据字符串为“strtok function testing” 按空格进行分割，
则需返回的结果是“strtok”，“function”，“testing”三个单词

代码实现

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


int _tmain(int argc, _TCHAR* argv[])
{
    //char input[64] = {"   sfsf  n8784b55632656   6525   558456 5222      "};
    char strBuffer[128] = {0};
    char *pStr = NULL;
    FILE *hFile = NULL;

    hFile = fopen("stringfile.txt", "rb");
    if(NULL == hFile)
    {
        printf("open file failed\n");
        return 0;
    }

    while(fgets(strBuffer, sizeof(strBuffer), hFile) != NULL)//逐行读取文件的数据
    {
        pStr = strtok(strBuffer," ");//按空格进行分割
        while(pStr)
        {
            printf("string: %s\n",pStr);
            pStr = strtok(NULL," ");//按空格进行循环分割获取所有字符串
        }
    }

    if(hFile)
    {
        fclose(hFile);
        hFile = NULL;
    }

    system("pause");

    return 0;
}
