Last update on December 20 2024 13:16:09 (UTC/GMT +8 hours)

Write a program in C to print the current date and time.

Sample Solution:

C Code:

#include <time.h>
#include <stdio.h>
#include <stdlib.h>

int main(void) {
    time_t cur_time; // Variable to hold the current time
    char* cur_t_string; // String to store the formatted time

    cur_time = time(NULL); // Get the current time
    if (cur_time == ((time_t)-1)) {
        // Check for failure in getting the current time
        (void) fprintf(stderr, "Failure to get the current date and time.\n");
        exit(EXIT_FAILURE);
    }

    cur_t_string = ctime(&cur_time); // Convert the current time to local time format
    if (cur_t_string == NULL) {
        // Check for failure in converting the current time to string format
        (void) fprintf(stderr, "Failure to convert the current date and time.\n");
        exit(EXIT_FAILURE);
    }

    // Print the current time
    (void) printf("\n The Current time is : %s \n", cur_t_string);

    exit(EXIT_SUCCESS);
}

Sample Output:

 The Current date and time is : Thu Aug 03 13:38:58 2017

N.B.: The result may vary for your current system date and time.
