Date And Time in C++
The C++ standard library will not provide any proper date type. C++ inherits the structures and functions for date and time manipulation from the C language. Accessing of date and time with related functions and structures that is to use include a header file in your C++ program named time’s.
There are four time-related types which is defined.: clock_t, time_t, size_t, and tm. The types clock_t, size_t and time_t are the type mof clock which is capable of representing the system time and date as some sort of integer.
The tm structure is very important when working with the date and time in either C or C++ language. This structure holds the date and time in the form of a C structure. Most of the time related functions makes use of tm structure. let's take some examples on date and time in C++ for complete understanding on C++ date and time.
C++ Date and Time Example
This C++ program simply prints the local and UTC date and time on the screen.
{'/* C+ Date and Time - Example Program of C++ Date and Time'}
* This program prints local date and time, UTC date and
* time on the output screen */
Example
Here is the sample output of the above C++ program:
Current Date and Time
C++ Date Example
This C++ program prints the current date on the output screen.
{'/* C++ Date and Time - Example Program of C++ Date and Time'}
* This program prints today's date on the output screen */
C++ Time Example
This C++ program prints the current time on the output screen.
{'/* C++ Date and Time - Example of C++ Date and Time'}
* This program prints current date on the output
* output screen in C++ */
Format Time using struct tm
size_t strftime (char* ptr, size_t maxsize, const char* format, const struct tm* timeptr );
Format time as string
String Copies the pointer element ptr to the content of format, expanding its format specifier which is formed into the corresponding values that represent the time described in timeptr, with a limit of maxsize characters.
