Answer 1

fp=fopen("C:\server.txt","r");
-->
fp=fopen("C:\\server.txt","r");

Answer 2

void output();这句是何意？早明? 调用？

Answer 3

打错字，不好意思
void output();这句是何意？申明? 调用？

Answer 4

我想在 main中调用 output（）这个函数

}楼猪你懂的...

Answer 7

编译器为 VC++6.0主函数中为什么不能调用output()函数

Answer 8

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

  bool   data_ready = false;
  char   c;void output()
{
   printf("-------------------------Output--------------------------\r\n\r\n");        
   printf("%s",data_buf);   data_buf[0] = '\0';

  output();
 while(!feof(fp))
 {
     int result = 0;
     c =fgetc(fp);
    //    printf("%c",c);
      if(get_data)
      {
        if(data_ready)
        {
            data_buf[data_len++] = c;  //将接收的数据存入data_buf[]中    
        }
         result=memcmp(data_buf,"GPGSA",5);
        switch(c)
         { 
            case 0x24:  //开始符'$'
              data_len = 0;
              data_ready = true;
         
                 break;
            case 0x0a:  //结束符,回车
                if(result == 0)
                {
                get_data = false;
                
                printf("%s",data_buf);
                printf("/*---------------------data_buf-----------------*/\r\n");
              //  data_buf[0] = '\0';
                output();
                }
               break;
            default:
                break;
        }
        
       if (data_len>DATA_MAX_LEN)
       {
            data_len = 0;
            get_data = true;
            data_ready = false;
       }
      }
 }
   system("pause");
   fclose(fp);
}嗯 这次全了...

Answer 9

6楼的还是不行啊  不能调用output（）啊还有错误的输出啊

Answer 10

void output();是声明，不是调用，要去掉void

Answer 11

我的分类呢
$GPGGA      $GPGSV     $GPRMC来区分呢  有更好的优化代码写出来么   谢谢啦！！

Answer 12

在main函数前预定义函数原型，这是C++的形式；要不把整个output函数移动到main函数之前就可以了！ok！
