While the C standard library does not provide direct functions for date arithmetic, you can manipulate dates using the time.h library, specifically working with the time_t data type and struct tm.

time_t
struct tm
C doesn’t have a built-in type for dates, necessitating the use of the time.h library to work with date and time structures.
The strftime function from the <time.h> library is commonly used for this purpose.
strftime
<time.h>
In C, the <time.h> header provides the necessary functions and types to work with dates and times.
C doesn’t provide a built-in way to parse dates from strings directly, so we often resort to the strptime function available in the <time.h> library for POSIX systems.
