Dear Sir,

I am running c++ program in linux and to calulate computational time . I have given "time ./a.out" which gives elapsed time say suppose 1 hr 30 min with 75% CPU which is not appropriate commutaional time . How to find to correct computational time . Is there any other command.

use clock function

int timer clock(); ur code here ................. timer = clock() ; cout<<(timer/(float)1000000) <<endl;

gives the time taken for ur code in secs

Dear Ramesh ,Thank you very much. I will try.
