n this lab, you will time a simple C program with different compiler
options. In order to do this lab, you will need to know how to set various

download and install Cygwin to get a UNIX environment. gcc has different
optimization levels, which are controlled by -O option, with -O0 as no
optimization and -O3 as the highest level of optimization. Consult the man
pages for the detailed settings of the compiler.
