Question: How do I write code to retrieve current date and time from the system and display it as a string?
Answer: Use time( ) function to get current date and time and then ctime( ) function to display it as a string. This is shown in following code snippet.#include <systypes.h> void main( ) { time_t curtime ; char ctm[50] ; time ( &curtime ) ; //retrieves current time & stores in curtime printf ( "nCurrent Date & Time: %s", ctime ( &curtime ) ) ; } |
