Compile the program using gcc -o timing1 timing1.c -lm. Run the program 10 times with a command line argument of 5000000. Report the timings observed in the output. Repeat the process with arguments 10000000 and 20000000. Discuss the results observed, in particular regarding the resolution of the timing procedure used and the reproducibility of the results between runs. From the observed results, estimate the time needed to compute a square root.
