C Exercises: Convert a time_t object to a textual representation
C Date Time: Exercise-3 with Solution
Write a program in C to convert a time_t object to a textual representation.
Sample Solution:
C Code:
#define __STDC_WANT_LIB_EXT1__ 1
#include <time.h>
#include <stdio.h>
int main(void)
{
time_t result = time(NULL);
printf("\n%s\n", ctime(&result));
#ifdef __STDC_LIB_EXT1__
char time_str[26];
ctime_s(time_str,sizeof time_str,&result);
printf("\n%s\n", time_str);
#endif
}
Sample Output:
Thu Aug 03 13:44:49 2017
N.B.: The result may varry for your current system date and time.

How I can print to stderr in C?
The syntax is almost the same as printf. With printf you give the string format and its contents i.e.:
printf("my %s has %d chars\n", "string format", 30);
With fprintf it is the same, except now you are also specifying the place to print to:
File *myFile; ... fprintf( myFile, "my %s has %d chars\n", "string format", 30);
Or in your case:
fprintf( stderr, "my %s has %d chars\n", "string format", 30);
