Hi Tanuj,

 the code is a simple function that gets called 300000000 times.

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

int my_function (int a, char *buf)
{

   int  int_1 = 1987;
   char char_1 = 'a';
   long long_1 = 123456789L;
   long long_2 = &long_1;

   if (a > 0)
   {
       a++;
   }
   else
   {
       a--;
   }
   if (int_1 > 9)
   {
       char_1++;
   }
   else
   {
       char_1--;
   }
   *long_2++;
   if (buf == NULL)
   {
       return -1;
   }
   buf++;
   return a;
}


void main (void)
{

   long i;
   int result;
   char buf[8];
   clock_t start;
   clock_t stop;
   double  duration;

   buf[0] = 0;

   start = clock();
   for (i = 0; i < 300000000; i++)
   {
        result = my_function(10,buf);
   }
   stop = clock();
   duration = (double) (stop - start) / CLOCKS_PER_SEC;

   printf("the test lasted for %2.4f seconds\n\r",duration);
}
