C++ Exercises: Display the current date and time

Sample Solution:

C++ Code :

#include<iostream> // Including input-output stream header file
#include<cmath> // Including the header file for math functions
#include <ctime> // Including the header file to work with date and time

using namespace std; // Using the standard namespace

int main() // Start of the main function
{
    time_t t = time(NULL); // Declaring a time_t variable and assigning the current time to it
    tm* tPtr = localtime(&t); // Creating a pointer to a tm structure and obtaining the local time

    cout << "\n\n Display the Current Date and Time :\n"; // Outputting a message indicating the purpose of the program
    cout << "----------------------------------------\n"; // Outputting a separator line

    // Outputting different components of the current date and time
    cout << " seconds = " << (tPtr->tm_sec) << endl; // Displaying seconds
    cout << " minutes = " << (tPtr->tm_min) << endl; // Displaying minutes
    cout << " hours = " << (tPtr->tm_hour) << endl; // Displaying hours
    cout << " day of month = " << (tPtr->tm_mday) << endl; // Displaying day of the month
    cout << " month of year = " << (tPtr->tm_mon)+1 << endl; // Displaying month of the year
    cout << " year = " << (tPtr->tm_year)+1900 << endl; // Displaying year
    cout << " weekday = " << (tPtr->tm_wday) << endl; // Displaying weekday
    cout << " day of year = " << (tPtr->tm_yday) << endl; // Displaying day of the year
    cout << " daylight savings = " << (tPtr->tm_isdst) << endl; // Displaying daylight savings

    cout << endl; // Outputting empty lines for formatting

    // Displaying current date and time in a formatted manner
    cout << " Current Date: " <<(tPtr->tm_mday)<<"/"<< (tPtr->tm_mon)+1 <<"/"<< (tPtr->tm_year)+1900<< endl; // Displaying the current date
    cout << " Current Time: " << (tPtr->tm_hour)<<":"<< (tPtr->tm_min)<<":"<< (tPtr->tm_sec) << endl; // Displaying the current time

    cout << endl; // Outputting empty line for formatting

    return 0; // Returning 0 to indicate successful program execution
}

Sample Output:

 Display the Current Date and Time :
