03 March 2022 09:45:03 AM TIMER_CLOCK C++ version Demonstrate the use of the CLOCK timer. CLOCK is a C++ library routine (defined in ) It returns the processor time used by the program since the beginning of program execution. Divide this by CLOCKS_PER_SEC to convert to seconds. CLOCK is a crude timer, and results less than a tenth of a second are probably not reliable. The number of clock ticks per second is 1000000 TEST01 Time the RAND function by computing N values. For a given N, repeat the computation 5 times. Data vectors will be of minimum size 1 Data vectors will be of maximum size 16777216 CPU times are in seconds.
