Kalendar u C++

Zadatak: U C++ kreirati kalendar za ovaj mjesec tako da izgleda kao kalendar c4 formata.....koristiti opciju switch case();.....

Rješenje:

#include <iostream>#include <iomanip>#include <ctime>

using namespace std;

bool IsLeapYear(const int year) {return ((year%400==0) || (year

%4==0 && year%100!=0));}

int GetDaysInMonth (const int year, const int month) {

switch (month) {case 2: return IsLeapYear(year) ?

29 : 28;case 4:case 6:case 9:case 11: return 30;

default: return 31;}

}

int FirstDayOfMonth(const int year, const int month) {

// 0 = Sundaystatic int t[] = {0, 3, 2, 5, 0,

3, 5, 1, 4, 6, 2, 4};int y = year - (month < 3);return (y + y/4 - y/100 + y/400 +

t[month-1] + 1) % 7;}

void ShowCal(const int year, const int month) {

static const char *monthName[] = {"January","February","March","A

pril","May","June","July","August","September","October",

"November","December"};

int days = GetDaysInMonth(year, month);

int dow = FirstDayOfMonth(year, month);

cout << monthName[month-1] << " " << year << endl;

cout << " Sun Mon Tue Wed Thu Fri Sat" << endl;

cout << " --- --- --- --- --- --- ---" << endl << " ";

for (int day=0; day<dow; day++) { cout << " "; }

for (int day=1; day<=days; day++) {

cout << setw(3) << day << " ";if (++dow>6) {

dow = 0;cout << endl << " ";

}}cout << endl;

}

int main(int argc, char** argv) {// test on todaytime_t curtime = time(NULL);struct tm *loctime =

localtime(&curtime);ShowCal((loctime->tm_year + 1900),

(loctime->tm_mon + 1));

return 0;}
