/****************************************** Author: Nautash Ahmad Created: 15th October, 2018 ------------------------------------------- Description: Want to know how old are you? Then enter your birth date and check what is your age in Years, Months, Weeks and Days. Also check out how much you spent your life in Hours, Minutes and Seconds. ------------------------------------------- Note: First you need to enter the Current Date in the DD/MM/YYYY format and then enter your Birth Date in DD/MM/YYYY format. Sample input: 20/02/2018 In case you didn't input the date in the specified format or if the date exceeds from the limit i.e if the month entered is 15 or if the days entered are 35 the program will output error and will ask again for the correct input. The code might not work in Sololearn sometimes giving the Compilation Error. But it works absolutely fine, tested it on other compilers. For better experience use some other compiler. If the code gives Compilation Error here in CPG, then you need to run this code on different compiler. ******************************************/ #include #include #include #include using namespace std; struct Date { int date; int month; int year; }; bool FormatValidation(string str); Date FiguresSeperator(string str); bool FiguresValidation(struct Date d, bool isCurr, int year); int main() { struct Date curDate; string str; //Inputting the current date bool isCorrect = false; cout << "Enter the current date in the DD/MM/YYYY format\n"; do { cin >> str; cout << endl; if(FormatValidation(str)) { curDate = FiguresSeperator(str); bool isOK = FiguresValidation(curDate, true, 0); if(isOK) { cout << "\nCurrent Date: " << curDate.date << "-" << curDate.month << "-" << curDate.year << endl; isCorrect = true; } else { cout << "Enter the correct date figures.\n"; isCorrect = false; } } else { cout << "Enter the date in the correct format.\n"; isCorrect = false; } }while(isCorrect == false); struct Date birDate; //Inputting the birth date isCorrect = false; cout << "\n\nEnter your birth date in the DD/MM/YYYY format\n"; do { cin >> str; cout << endl; if(FormatValidation(str)) { birDate = FiguresSeperator(str); bool isOK = FiguresValidation(birDate, false, curDate.year); if(isOK) { cout << "\nBirth Date: " << birDate.date << "-" << birDate.month << "-" << birDate.year << endl; isCorrect = true; } else { cout << "Enter the correct date figures.\n"; isCorrect = false; } } else { cout << "Enter the date in the correct format.\n"; isCorrect = false; } }while(isCorrect == false); struct Date age; //Initializing an array of months with their respective days int monthDays[] = {31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31}; //Calculating the dates/days if(birDate.date > curDate.date) { curDate.date += monthDays[curDate.month-1]; age.date = curDate.date - birDate.date; curDate.month -= 1; } else { age.date = curDate.date - birDate.date; } //Calculating the months if(birDate.month > curDate.month) { curDate.month += 12; age.month = curDate.month - birDate.month; curDate.year -= 1; } else { age.month = curDate.month - birDate.month; } //Calculating the years age.year = curDate.year - birDate.year; //Calculating leap years int leapYearDays = age.year / 4; //Adding day of each leap year age.date += leapYearDays; //Checking if days of age exceeds from the month days if(age.date >= monthDays[age.month-1]) { age.date = age.date - monthDays[age.month-1]; age.month += 1; } //Calculating the weeks int weeks = age.date / 7; age.date = age.date % 7; cout << "\nYour age including leap years is: " << age.year << " yrs, " << age.month << " months, " << weeks << " weeks and " << age.date << " days\n"; //Calculating total days and hours size_t lifeDays = (age.year * 365) + leapYearDays; size_t lifeHours = lifeDays * 24; cout << "\n\nLife spent in hours: " << lifeHours << " hrs." << endl; //Calculating total minutes size_t lifeMins = lifeHours * 60; cout << "Life spent in minutes: " << lifeMins << " mins." << endl; //Calculating total seconds size_t lifeSecs = lifeMins * 60; cout << "Life spent in seconds: " << lifeSecs << " secs." << endl; return 0; } //This function checks the format of date bool FormatValidation(string str) { regex e("[[:d:]]{2}/[[:d:]]{2}/[[:d:]]{4}"); bool match = regex_match(str, e); return match; } //This function separate the date parts into date, month and year respectively and save them to structure Date FiguresSeperator(string str) { struct Date d; char *ch = new char[str.size()+1]; int *temp = new int[3]; int index = 0; //Tokenizing the date strcpy(ch, str.c_str()); char *p = strtok(ch, "/"); while(p) { temp[index] = atoi(p); p = strtok(NULL, "/"); index++; } //Assigning values to the structure d.date = temp[0]; d.month = temp[1]; d.year = temp[2]; delete[] temp; delete[] ch; return d; } //This function check the limits of date bool FiguresValidation(struct Date d, bool isCurr, int year) { bool correctDate = false, correctMonth = false, correctYear = false; //Checking the date limits if(d.date > 0 && d.date <= 31) correctDate = true; //Checking the month limits if(d.month >= 1 && d.month <= 12) correctMonth = true; if(isCurr == true) correctYear = true; else { //Checking if birth year is less than or equal to current year if(d.year <= year) correctYear = true; } if(correctDate == true && correctMonth == true && correctYear == true) return true; else return false; }
