The returned value generally indicates the number of seconds since 00:00, January 1, 1970 UTC, also known as the Unix timestamp. Although libraries may use a different time representation, programs should not use the value returned by this function directly!
In this code, first the start time of the loop is recorded with start_t = clock(), then the loop is iterated, and finally the end time is measured with end_t = clock(). The difference between end_t and start_t returns the measured CPU time in ticks. This value is divided by CLOCKS_PER_SEC to convert the time to seconds. The result is stored in total and then printed using printf. Please note that you need to add the code for your actual loop in the comment where the loop is placed.
On a 32-bit system where CLOCKS_PER_SEC is 1000!
You want to measure the time taken by a large loop in your C code. Your code uses the clock() function from the C standard library to measure CPU time. A
