You are going to have to narrow down the problem a bit more for us -- where is the problem? Don't expect us to wade through hundreds of lines of code to find it ourselves. Ain't going to happen.

line 204...sry

[kcys.wong]

my input line 204 is not functioning...the programme skip to next command

[NathanOliver]

give this article a look.

[kcys.wong]

ty,nathanoliver....but still the article is too hard for me to understand

[Ancient Dragon]

When you enter a numeric type such as integer or float you have to press the <Enter> key, which is represented in the program as '\n'. Then cin processes the keystrokes one at a time and stores valid numbers in the numeric data. It stops converting when cin encounters the first non-valid character, such as that enter key '\n' and returns control to your program. That leaves the keyboard buffer in an unknown and unpredictable state, so before continuing the program needs to flush out all remaining keys.

In c++ there is an easy way to flush the keyboard buffer, which is explained in detail in that link that Nathan prosted. Yes there is some complicated theory in Narue's article, but the only part you need is at the very beginning

#include <ios>
#include <istream>
#include <limits>

void ignore_line ( std::istream& in )
{
  in.ignore ( std::numeric_limits<std::streamsize>::max(), '\n' );
}

With the above, just call ignore_line() after the calling cin that gets an integer or float. For example:

cout<<"Please enter the time(hh mm)"<<endl;
        cin>>task[count].hour;
        cin>>task[count].minute;
        ignore_line(cin); // <<<<< Flush keyboard buffer

[kcys.wong]

in.ignore ( std::numeric_limits<std::streamsize>::max(), '\n' );
this line has syntax error ')'

[Ancient Dragon]

what error message did you get? Did you add the includes that I posted? what compiler are you using?
