How to test a run-time of a C program
 
Hi everyone,

I have two little programs I wrote in C. They both do the same thing but the code is different. How would I go about testing which runs faster?

Try the "time" program. This is probably only useful if your program does not require user input though.

Code:

time ./a.out
and compare the times for each run.

There's time(1) and the shell builtins "time" and "times". Use "help time" and "help times" to see their descriptions.
