C++ Exercises: Display the current date and time

Sample Solution:

C++ Code :

#include<iostream>
#include<cmath>
#include <ctime>
using namespace std;

int main()
{

 time_t t = time(NULL);
 tm* tPtr = localtime(&t);
 cout << "\n\n Display the Current Date and Time :\n";
 cout << "----------------------------------------\n";
 cout << " seconds = " << (tPtr->tm_sec) << endl;
 cout << " minutes = " << (tPtr->tm_min) << endl;
 cout << " hours = " << (tPtr->tm_hour) << endl;
 cout << " day of month = " << (tPtr->tm_mday) << endl;
 cout << " month of year = " << (tPtr->tm_mon)+1 << endl;
 cout << " year = " << (tPtr->tm_year)+1900 << endl;
 cout << " weekday = " << (tPtr->tm_wday )<< endl;
 cout << " day of year = " << (tPtr->tm_yday )<< endl;
 cout << " daylight savings = " <<(tPtr->tm_isdst )<< endl;
        cout << endl;
        cout << endl;


        cout << " Current Date: " <<(tPtr->tm_mday)<<"/"<< (tPtr->tm_mon)+1 <<"/"<< (tPtr->tm_year)+1900<< endl;
        cout << " Current Time: " << (tPtr->tm_hour)<<":"<< (tPtr->tm_min)<<":"<< (tPtr->tm_sec) << endl; 
           cout << endl;
    return 0;
}

Sample Output:

 Display the Current Date and Time :

 day of year = 186                                                     
 daylight savings = 0                                                  
                                                                       
                                                                       
 Current Date: 6/7/2017                                                
 Current Time: 12:33:57

Why is there no std::stou?

The most pat answer would be that the C library has no corresponding "strtou", and the C++11 string functions are all just thinly veiled wrappers around the C library functions: The std::sto* functions mirror strto*, and the std::to_string functions use sprintf.
