Question

How to get the current time as h:m:s in C

Answer 1

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

// size_t strftime(char *str, size_t maxsize, const char *format, const struct tm *timeptr)

int main() {
    time_t t = time(NULL);

    struct tm dt = *localtime(&t);

    printf("%d-%02d-%02d %02d:%02d:%02d\n", dt.tm_year + 1900, dt.tm_mon + 1, dt.tm_mday, dt.tm_hour, dt.tm_min, dt.tm_sec);

    char buffer[32];

    strftime(buffer, sizeof(buffer), "%X", &dt); 
    puts(buffer);

    return 0;
}
