help needed !!

mdk85 (36)
i am working on reminder/to do list program . i am not able to finish it .. the data's are given which is in main function .. so when the data is inputted , the data should match the data which is given in main function with its message , date and time ..
the time is declared from 0 to 23 for hours and 0 - 59 for minutes . so when the user enters the number other than given numbers say (24forhours ) that function should ask the user enter the hours again since the hours can be given only between 0 - 23 . i dont know how to do that .The function it is in time class . input()

if I understand you can do something like that:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
 
void time::input()
{
    cout<<"\nEnter hour"<<endl;

//idea:
do{  
            cin>>hour;
}while(hour>23 || hour <0)
      

    cout<<"\nEnter min"<<endl;
//do the same before:
    cin>>min;
}
mdk85 (36)
i think it should be 
 
 
while(hour>0 || hour<23)


since it should be b/w 0 and 23 not more than 23 :)

did u got the idea about the other problem which i am facing ??
Aikon (75)
I think my ask is correct:

1
2
3
4
 
do{  
            //cout <<"put a correct hour" << endl;
            cin>>hour;
}while(hour>23 || hour <0)


While the user dont put a correct answer your program will still ask a good answer.


About the other program I'm not sure what is your problem, my english isn't too good if you could explain it slowly.
mdk85 (36)
there is one more problem in output window the date format should be 28 may 2011 and when the user enters 1 to view all the reminders the date format should be 28/5/2011 .

i have to use objects within objects dont know how to do that

I suggest the inputs of your program will be strings for void error of input and after transform to int unless you use excepcions.

You could use somthing like this:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
 
void date::input()
{
           ...
           int aux;

           cout << "Select 1 for see short format or any number for long"<<endl;
           cin>>aux;

           switch (aux)
          {
