實現功能:

01. 純C一次讀一行文字檔案內容(去除換行符號)
02. 純C建立對應BAT命令檔
    使用BAT刪除特定檔案目錄下所有檔案(刪除所有Cookies)
    指定opera.exe開啟對應三個網頁
03. 執行建立好的BAT

Code:

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

int main()

    FILE *pf01;

    pf00=fopen("Run.bat","w");
    pf01=fopen("List.txt","r");
    while(fgets(buf0,10,pf01) != NULL)
    {
        for(j=0;j<10;j++)
