How can I make a user wait before being able to use a function again?

I'm sure this has already been answered somewhere but I can't find..

I am new to programming so I need help! Thank you !!

Solution

  • You could use a static time variable inside a function: 

    void work()
{
  static bool      first_pass = true;
  static Time_Type unlock_time;
  if (first_pass)
  {
      // Assign unlock time to now.
      // Add 3 minutes to unlock time;
  }
  else
  {
     Time_Type time_now = /* ... */;
     if (time_now > unlock_time)
     {
         // unlock_time = time_now + 3 minutes;
         // Remaining function goes here.
     }
  }
}

    Static variables inside a function keep their values after execution leaves the function.

    For time functions and variables, see std::chrono.
