Thread: Simple switch case with date not working

I am having a problem type casting my strftime buffer to work with my switchcase statement. Switchcase only uses string/char/int variable, However stftime is something along the lines of a date type variable, so it's not working with my switch case statement.

In short, I need to convert my strftime buffer variable into a char variable to print the correct day of week.

Code:

#include <stdio.h>     
#include <time.h>       /* time_t, struct tm, time, gmtime */

int main ()
{
  // Get a tm structure
  time_t now = time(NULL); 
  struct tm *tick_time = localtime(&now);
  
  // Create a long-lived Time buffer
  static char buffer[0];  
  strftime(buffer, sizeof("0"), "%u", tick_time); 

 
  char p = atoi(buffer);
  
   switch(p)
   {
   case '1' :
      printf ("mo");
      break;
   case '2' :
       printf("tu");
      break;
   case '3' :
      printf("wed");
      break;
   case '4' :
      printf("th");
      break;
   case '5' :
      printf("fr");
      break;
    case '6' :
      printf("sa");
      break;
     default :
       printf("su \n");
   }

printf(buffer);
    

  return 0;
}

Help would be greatly appreciated.
