Answer 1

#include <stdio.h>
 
int main(void)
{
    unsigned long microseconds = 49198630575; 
     
    long milliseconds = (long)(microseconds / 1000) % 1000;
    long seconds = (((long)(microseconds / 1000) - milliseconds) / 1000) % 60;
    long minutes = (((((long)(microseconds / 1000) - milliseconds) / 1000) - seconds) / 60) % 60;
    long hours = ((((((long)(microseconds / 1000) - milliseconds) / 1000) - seconds) / 60) - minutes) / 60;

    printf("%ld:%ld:%ld.%ld\n", hours, minutes, seconds, milliseconds);
   
    return 0;
