Hi, here I included my code to find no of working days between two years. But in leap year I do not know how to find the working days. Can anyone help me? function calculate($month,$year) { $Start_Date="1/".$month."/".$year.""; $myTime = strtotime($Start_Date); // Use whatever date format you want $daysInMonth = cal_days_in_month(CAL_GREGORIAN, $month, $year); // 31 //$workDays = 0; while($daysInMonth > 0) { $day = date("D", $myTime); // Sun - Sat if($day != "Sun" && $day != "Sat") $workDays++; $daysInMonth--; $myTime += 86400; // 86,400 seconds = 24 hrs. } return $workDays; } <?php echo calculate($MONTH,$YEAR)?> |

Hello friends. I want to create a countdown program for the new year that is comming. I know i can use this code for example, for short certain time: from threading import Timer def sayhi(): print "hello everybody!" t = Timer(10, sayhi) t.start() But the new year begins in 29 days (2015, march 21)(at 02:15:11 AM). So i cant calculate how many seconds is left!! So what can i do? I think i should give the date to the program and it should use a calendar maybe, but i don't know how. |

I want to copy all the files from one directory to another using the fread() and fwrite()-statements. Some of these files are rather large in size, and that's why I want to calculate who long the transfer will take. (Later I will use this information to show a progress bar containing remaining transfer time, percent data transferred so far and (possibly) the actual transfer speed). **The problem is:** When I try to do a full transfer of the biggest file in the list (the one with index 0 in the fdata-struct) I find that the transfer time is much higher … |

Alright so I'm coding a Quadratic Equation Solver to help with my Math Class. However the teacher requires each calculation to be written out. I have the solver working, however I'm not sure where to start when it comes to printing each step. I know I will need to `System.out.println()` each step. But how does Java interpret the equation? Does it do proper BEDMAS(Brackets, Exponents, Division, Multiplication, Addition, Subtraction)? if(disc == 0) { x1 = (-b+Math.sqrt(Math.pow(b, 2)-4*a*c))/(2*a); System.out.println("One Root Found: " + x1); } else if(disc > 0) { x1 = (-b+Math.sqrt(Math.pow(b, 2)-4*a*c))/(2*a); x2 = (-b-Math.sqrt(Math.pow(b, 2)-4*a*c))/(2*a); //Output Results System.out.println("Two … |

So this is what i need to do and its not coming out right in my code. i need A function to calculate how long the balance will take to grow to a given value. This function is not part of the account class. It should take two arguments: an object of the account class and a target value. It should return how long should pass until the balance on the account object reaches the target value.
