i am new in programming . i have a clock code. but want to modify it. when user press "0" it increment in time by 5min and when press "1" increment time by 10 min

Please use the code-tags.

And I don't quite understand your question. What do you mean with 'it runs clock 5 minutes'?

Edited 3 Years Ago by mike_2000_17: Fixed formatting

when user press "0" it increment in time by 5min and when press "1" increment time by 10 min

You could use a while loop.

char ch = ' ';
bool RepeatWhile = 1;
while(RepeatWhile) //Repeat while loop until something else then 0 or 1 is entered
{
  cin >> ch;
  switch(ch)
  {
    case '0':
      myClock.incrementMinutes(5);
      break;
    case '1':
      myClock.incrementMinutes(10);
      break;
    default:
      RepeatWhile = 0;
      break;
  }
}

Also change your current functions:

void clockType::incrementMinutes(int AMin)
{
  min = min + AMin;
  while (min > 59) //in case that min > 119
  {
    min = min - 60;
    incrementHours(1); //After you changed the function increment hours, otherwise use incrementHours();
  }
}

thanks for the help.but i didnt get ur point. where i have to do these changes.i have tried doing the cahnges but nothing can u please do these changes.thanks a lot for the help

The following code should work:

I changed it a bit. Instead of while loops I used / and %, which is more efficient. If you don't know I used them, then see it as a little homework. It isn't that hard to figure out ;)
