Homework and Emergencies Homework & Coursework Questions Time command issuing all zeroes (is now considered homework help) Post 302834137 by Corona688 on Thursday 18th of July 2013 11:42:11 AM

They didn't literally mean you to give it the arguments 'arg1' and 'arg2'. You're supposed to give it numbers -- they determine the data size and number of loops. Giving it the strings 'arg1' and 'arg2' cause them both to be zero, which makes it do no work -- zero loops over zero elements.

Code:
$ time ./program 1000 1000 >/dev/null


real    0m0.657s
user    0m0.655s
sys     0m0.002s
