If you run your program using the "time" program, it will display the time it took for the program to run. For example:

Code:

[machine:~]:time ls -al >> /dev/null

real    0m0.045s
user    0m0.016s
sys     0m0.028s

My question is where to write the code?
under the program itself or in the bash command line?
and my program is under C not C++...
