C以及C＋＋将输入任务存储到一个文本文档

设计的管理任务系统：直接上addtask的函数咯

然后检测是否有时间重复的任务，如果有的话便重新输入一遍

利用cin等函数实现输入任务  输入其他属性 如名字、优先级等等同时设置缺省值  

将任务属性存入文档 

void AddTask()
{
 char flag=1;//用flag来判定时间其是否重复
 char taskname[1000];
 char tasktime[13],tasktype[10]={0},taskpriority[10]={0};
 char str[512];
 FILE *out;
 out=fopen("/home/code/Desktop/Homework/task.txt","a+");
 cout<<"[ system prompt ] Please enter the time when the task begins(such as 202207080101) "<>tasktime;
  //判断是否存在相应tasktime
   fseek(out, 0, SEEK_SET);     //将文件指针移到文件头
     while( fgets(str, 500, out) != NULL )
      {
         str[12] = '';
         if( strcmp(str,tasktime) == 0 )
         {
          flag=0;    }}
 if(!flag)  {cout<<"< system warning ! > A task with the same start time already exists"<>tasktime;}

 tasktime[12] = '';
 //cout<<"[ system prompt ] Please enter the exact time when the task begins (such as 0708)"<>N;
 //cout<<"[ system prompt ] Please enter a reminder time for this task(such as 202304050203)"<>D;
 cout<<"[ system prompt ] Please enter the task name"<>taskname;
 cout<<"[ system prompt ] Please enter the task type(you can enter study, play and so on)"<* "<>tasktype;
 if(tasktype[0]=='*')
 {tasktype[0]='s';tasktype[1]='t';
 tasktype[2]='u';tasktype[3]='d';
tasktype[4]='y'; }
 cout<<"[ system prompt ] Please enter the task priority(you can enter high ,medium and low)"<*"<>taskpriority;
 if(taskpriority[0]=='*')
 {taskpriority[0]='l';taskpriority[1]='o';

 if(out!=NULL)
