Which one is taking more time and why ?
:/home/amaresh/Testing# cat time.c
//#include <stdio.h>
#define EOF -1
int main()
{
register int c;
while ((c = getchar()) != EOF)
{
putchar(c);
} return 0;
} -------------------
WIth stdio.h:-
:/home/amaresh/Testing# time ./time_header hi hi hru? hru?
real 0 m4.202s
user 0 m0.000s
sys 0 m0.004s ------------------
Witout stdio.h and with #define EOF -1 ===================
/home/amaresh/Testing# time ./time_EOF hi hi hru? hru?
real 0 m4.805s
user 0 m0.004s
sys 0 m0.004s
-- From above two case , why 2nd case is taking more time ?
