一、某些特定场景 ，如需要处理一些简单TXT文本文件，如串口数据时，则简单生成exe文件可以方便处理。

       简单的c文件参考如下，主要包含文件文件的打开、读取和保存等等。

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

FILE *fsmoke;
FILE *fppm;

void CreatFile(char *file_name)
{
}

int getTempValue(char *str)
{
	char slipe[] = ":";
	char *p = str;

	p = strtok(p, slipe);
	p = strtok(NULL, slipe);

	return atoi(p);
}

void getSmokeData(char *str, char *tempstr)
{
    char slipe[] = ":,";
    char *p = str;

    p = strtok(p, slipe);
    p = strtok(NULL, slipe);
    fputs("T=", fsmoke);
    fputs(tempstr, fsmoke);
    fputs(", ", fsmoke);
    fputs(p, fsmoke);
    fputs("\n", fsmoke);
    // printf("%s\n", p);
}

void getPpmData(char *str, char *tempstr)
{
    char slipe[] = ",";
    char *p = str;

    p = strtok(p, slipe);

    for (int i = 0; i < 4; i++)
        p = strtok(NULL, slipe);

    // printf("%s", p + 7);
    fputs("T=", fppm);
    fputs(tempstr, fppm);
    fputs(", ", fppm);
    fputs(p + 7, fppm);
}

int main(int argc, char *arg)
{
    char file_name[256] = "./a.txt";
    FILE *fp;
    DIR *pdir;
    struct dirent *pdirent;
    char StrLine[1024];
    char smoke_string[128];
    char ppm_string[128];
    char slipe[] = ":,";
	int TempValue = 0;
	int TempValue2 = 0;
    char TempStr[128];
    int Index = 0;

    if ((pdir = opendir("./")) != NULL)
    {
        while (pdirent = readdir(pdir))

    else

    }

    if ((fp = fopen(file_name, "r")) == NULL)

二、需要安装GCC，命令窗口下gcc -v可以查看     

  生成exe命令：gcc read.c  -o  test，即编译read.c生成test.exe.
