The Program in C++ Program to Compute Number of days of a month from a given year and month is given below:
#include <iostream>
using namespace std;
int main() {
int year, month;
cout << "Hello Codeauri Family,Enter year here : ";
cin >> year;
cout << "Similarly, Enter month From (1-12): ";
cin >> month;
int days;
switch (month) {
case 2:
days = (year % 400 == 0 || (year % 4 == 0 && year % 100 != 0)) ? 29 : 28;
break;
case 4:
case 6:
case 9:
case 11:
days = 30;
break;
default:
days = 31;
}
cout << "Well, the Number of days in month " << month << " of year " << year << ": " << days << endl;
return 0;
}
Output:
Hello Codeauri Family,Enter year here : 2023
Similarly, Enter month From (1-12): 1
Well, the Number of days in month 1 of year 2023: 31
Pro-Tips💡
This program uses a switch statement to determine the number of days in the month based on the value of month.
For February, it uses an if-else statement to determine whether the year is a leap year (i.e., a year that is divisible by 400 or divisible by 4 but not divisible by 100).
